Abstract
Vinyl chloride polymers are prepared by polymerizing a monomer component that comprises vinyl chloride in an aqueous medium in the presence of a free radical-generating polymerization initiator and 0.01% to 2% by weight, based on the weight of the monomer component, of a chain-transfer agent that is a mercapto organic compound having at least one beta-ether linkage. The process can be used to produce low molecular weight vinyl chloride polymers.
