Show the synthesis of a Dacron polyester fiber. Explain how to achieve the required stoichiometry and how to estimate the degree of polymerization of the intermediates while the reaction is proceeding b.
Show the synthesis of Nylon 66 including the intermediates which help establish the proper stoichiometry to form high molecular weight polymer. c.
Nylon 6 is synthesized by a ring opening polymerization so rapidly that it can actually be conducted by reaction injection molding (RIM). How is this process achieved? d.
Lexan is a polycarbonate useful in molding appliance housing. Assume that it can be made by an interfacial process, show the necessary components required for the synthesis and describe the technique
