Molecular weight enhancement of vinyl chloride–propylene copolymers

Authors


Abstract

The chain transfer activity of propylene leads to the formation of vinyl chloride–propylene copolymers with molecular weights lower than those of PVC homopolymers produced under similar conditions. It has been found that the addition of specified quantities of monomers with two or more active double bonds can increase the molecular weight of these copolymers without causing crosslinking.
