Abstract
Micro-suspension polymerization of vinyl chloride monomers and comonomers with a seed in the form of a previously prepared dispersion of the polymer or copolymer containing all of the organo-soluble initiator required for the polymerization, in which the initiator is activated during the polymerization by the addition of an organo-metallic complex of a water-soluble metal salt reacted with a complexing agent.
