Organic Chemistry Statement Of Inquiry: Scientists observe patterns and use them to construct systems that allow them to identify and relate the properties of molecules based on their functional group. Background to Polymers? These synthetic polymers can be produced in a wide variety, such as common plastics, nylons, or the surface of a non-stick frying pan. These man made polymers have a disadvantageous impact on the ecosystems. Polymers are often used in almost everything because of their physical properties like strong, resistant to corrosion, easy to shape, colour, and inexpensive. It is inexpensive for the users but leaves a huge scar to the environment that is very expensive to cover up. Petroleum is the main raw source of these polymers. …show more content…
What are the problems associated with synthetic polymers? The main problems associated with synthetic polymers are related to Environment, and these problems negatively affect the environment by pollution. The key idea of this problem is that these polymers do not breakdown therefore they harm the environment. They are also harmful for everybody’s health. Most polymers are non-biodegradable and this brings around the problem. Polyesterene, commonly known as Styrofoam. It is a non-biodegradable material. It takes centuries to decompose, and if it does it emits dangerous
The first level is description and it explains that systematic observation enhances the understanding of a certain phenomenon by allowing scientists to describe it in a more accurate way. In order to do so scientists need to collect data by observing the phenomenon of interest, record data, and examine all possible relations with other known facts. The information obtained from the description phase allows for the creation of hypotheses or questions to
• Lowering freight costs because of the light weight of plastics. • Plastics can be shaped and made in different patterns hence advantageous for marketing and shipping. • Plastics are made from natural resources such as

Today, polyvinyl chloride (PVC) is used in many different products across the world. According to the APHA (2011), the material can be found in toys, medical supplies, floors, and even food wrapping. (p. 1) I believe that this material has made it possible for a lot of products to be made that have benefited the human population, but I believe there are many drawbacks to using this material.
Service life The effect of fillers on polymers is that they are very beneficial because they don’t get ruined for a long time. Glass fillers are the most commonly used fillers in polymers. This is because they last longer and their service life is longer.
There is also debate on how much better biodegradable plastics are in the first place. This is because as biodegradable plastics break down, they break up into smaller and smaller pieces, but never quite disappear. This leaves the potential that the plastic would continue entering the food chain. But although biodegradable plastics aren’t perfect, they are still much safer than standard plastic and present a much lower risk. In addition, by making the shift to ban single use plastics, research towards better plastic alternatives will speed up and better solutions will become available. Over time, these new alternatives to plastics may spread to other items that aren’t single use, making an even greater impact on the health of humans and the
Although companies across the globe continue to produce multiple polycarbonate #7 plastic products with BPA, more is being noticed about the adverse health effects to humans can be harmful. Testing on mice has proven that some exposure to BPA can be linked to Cancer and neurological disorders. In countries which have banned the use of BPA in different products, would agree that this chemical is toxic and dangerous. However, as long countries like the United States, who do not currently support banning BPA countrywide due to limited scientific data to back all claims, BPA will continue to be a global issue which continues to be hidden in the dark and a mystery globally
The synthesis of polymers starts with ethylene, (or ethene). Ethylene is obtained as a by-product of petrol refining from crude oil or by dehydration of ethanol. Ethylene molecules compose of two methylene units (CH2) linked together by a double carbon
chains instead of hydrogen atoms. Cross-linking is another way in which the polymer can be made stronger. This involves ultraviolet radiation that bombards the polymer with electrons and formulates bonds between the molecular chains of the polymers. This is like linear polyethylene but different in that it is more impact resistant, and it has a much higher density. This allows it to be stored or be used with different chemicals that would normally cause the polymer to desolve.3 This can start to become a problem because as the polymer continues to become chemically enhanced. So the ways of dissolving and recycling the polymer become more difficult.
...can also cause a negative impact on the environment. The manufacturing of synthetic-based health products may release chemicals in the air and water, which can cause pollution and damage to the surroundings. On the other hand, natural health products are farmed and manufactured organically, so you can be sure that these products do not contribute to air and water pollution.
1- collection of related chemical data from different sources, arranging the data and storing it into special chemical libraries and databases.
These fragments absorb all the toxins that pollute waterways, contaminate soil, and sicken animals (which are then consumed). Plastic trash also absorbs organic pollutants such as BPA. They take centuries to decompose while sitting in landfills, amounting to billions of environmentally poisonous time bombs. Bisphenol A (BPA) is a chemical compound used to create polycarbonate plastic and epoxy resins. Polycarbonate plastics are found in a wide range of products, but food and drink containers are the most concerning.
Recycling is the process by which a waste material is converted again into reusable process and disposal is a process by which we get rid of something. Polymers are not very reactive so this property makes them very useable for storing food but this property makes it difficult to recycle or dispose of polymer. This difficulty in recycling and disposing of polymer is a major cause of environment hazard. Since the waste of polymer is increasing day by day so proper measurement should be taken to reduce the use of polymer and different method should be made to properly dispose and recycle waste. Following are the process by which a polymer is recycled or disposed.

Plastics are being used in so many different ways. Whether you are aware of it or not, plastics play and important part in your life. Plastics' versatility allow it to be used in everything from car parts to doll parts, from soft drink bottles to the refrigerators they are stored in. From the car you drive to work in to the television you watch when you get home, plastics help make your life easier and better. So how is it that plastics have become so widely used? How did plastics become the material of choice for so many varied applications? The simple answer is that plastics are the material that can provide the things consumers want and need. Plastics have the unique capability to be manufactured to meet very specific functional needs for consumers. So maybe there's another q...
