Teflon can be made from tetrafluoroethylene by means of a free radical polymerization . In the reaction, termination occurs only by combination and not by disproportionation. It is to be explained above observation. Concept introduction: In any free radical polymerization reaction generally, three steps are involved viz. 1) initiation, 2) propagation, and 3) termination. In initiation step, free radicals are generated from either monomer or from another compound such as hydrogen peroxide or benzoyl peroxide called a radical initiator. In propagation, step radicals react with the monomer to grow the chain to build up polymer and this process is called a chain-growth polymerization or addition polymerization. Finally, in terminating step, the growth of polymer is stopped by two ways: combination or disproportionation. In combination step, two growing polymer radicals combine to form the uncharged product, polymer. The termination occurs when the one radical ion abstracts a proton atom from another radical ion is called disproportionation.

Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
