Abstract
Copolymers of vinyl or vinylidene halides and vinyl esters of C.sub.2 and C.sub.3 acids are provided having low molecular weights, good particle characteristics, and improved melt flow are made by aqueous polymerization utilizing an effective amount of a mercaptan as a chain transfer agent, wherein the chain transfer agent is admixed with the vinyl esters to form a chain transfer composition, and may be added before the start of the polymerization.
