FIELD: chemical technology, polymers.
SUBSTANCE: invention relates to a method for polymerization of a polymerizing mixture containing vinyl chloride monomer. Method involves addition at least one organic initiating agent with half-time decomposition value in the range 0.0001-1 h, and 0.01-1 wt.-% of protecting colloid to polymerizing mixture at the polymerization temperature. Method provides improving regulation of polymerization rate and enhanced yield of the end product for one running of reactor per time unit, and preparing polymer with relatively high porosity index.
EFFECT: improved method of polymerization.
