Abstract
Method of polymerizing vinyl chloride with one of the ethylene or propylene olefins in a suspension polymerization system, characterized in that the vinyl chloride is added in portions to the olefin-containing system, said system having a pH of 3. at 11, a temperature of 5 to 95º C and a pressure of 100 to 1,000 psi (7.03 to 70.3 kg/cm 2) to form a copolymer having an olefinic content of at least 2% ethylene or 1% propylene and an average molecular weight, expressed as intrinsic viscosity, of 0.5 to 1.5 dl/gram and a melt flow rate of at least 0.5 dg/minute.
