One of the following is true not about chain and step growth polymerization. Group of answer choices A. Unsaturated monomers undergo chain growth polymerization whereas monomers with two more functionality undergo step polymerization. B. The molecular weight of the mer and the monomer are the same in both polymerization methods. C. In chain growth polymerization very large molecular weight polymer can be produced very quickly whereas in step growth polymerization large molecular weight polymer is formed when nearly all monomers are consumed. D. An initiator is needed for chain polymerization but nor for step polymerization. E. All are correct.
