Solution and bulk properties of branched polyvinyl acetates part II--Synthesis of some branched polyvinyl acetates

Abstract

A series of comb-shaped branched polyvinyl acetates has been prepared by a graft polymerization technique. Branches of a specified average chain length have been grafted to a linear backbone polymer with a narrow molecular weight distribution. The branched polymers have a molecular weight distribution whose breadth is very close to the linear fraction used for the backbone chain. The number average molecular weight of the branches has been varied from 18 000 to 106 000. The molecular weight of the linear backbone polymers is of the order of one million.
