Synthesis of Linear High Molecular Weight Polyvinyl Acetate by Raft Polymerization
Polyvinyl acetate has wide range of application in fibers, films and protective colloids. Because of the very high
reactivity of the propagating radicals makes VAc one of the most challenging monomers for RAFT polymerization. Use of a
proper RAFT agent allows synthesis of polymers with low polydispersity index (PDI) and high functionality, but high
molecular weight polymers cannot be obtained because of reduced propagating rate. In this paper, some of the most
important methods for obtaining linear high molecular polyvinyl acetate via RAFT method is investigated.
