FIELD: chemistry.
SUBSTANCE: invention discloses a polymerisation method involving the following steps: (a) reacting aqueous suspension containing an initiator, vinyl chloride and optionally one or more copolymers in a continuous action mixing reactor; and (b) further reaction of the obtained suspension in at least one second reactor; where the degree of conversion of vinyl chloride in the continuous action mixing reactor at step (a) ranges from 10 to 40 wt %.
EFFECT: invention can be used to produce copolymers with excellent heat resistance and constant particle size distribution of the obtained polyvinyl chloride(D50=150 mcm).
