- What structura! features make polymer to be thermo and thermosetting polymers? Explain with one example for each. Once you upload files from your second device, click on CSymThis is not really a question but, I have a presentation to do on one of the following polymers. I was just wondering if you can pick the top 5 best out of them all. I will include the questions I will be researching, I just want an expert opinion on which polymer would be th best for these questions. :) These are the questions that I will be resaerching about: List its current uses and why we use it for those applications. What is it? What are its components (i.e., its monomers)? How is the polymer manufactured? What is the chemical reaction that occurs in its creation? What is the chemical reaction that occurs in its degradation? What are the environmental consequences of its production? What are the environmental consequences of its disposal? Propose a solution to the environmental consequences you listed above. For example, could something about the polymer be changed to alleviate the problems or could another, safer polymer be used in its place? And these are the polymers I…Scenario Four Read the following extract: "A polymer is a substance which has a molecular structure comprising of a large number of identical molecules covalently bonded together to form a long chain structure. Many synthetic organic materials are polymers, such as nylon, polythene and Kevlar." The extract mentions 'covalent bonds'. Explain what these are, and the formation of different types that can exist i.e. single, multiple etc. Do some research and identify 4 simply covalently bonded molecules. Draw dot and cross diagrams of each to show the bond formation of each of your 4 examples.
