FIELD: chemistry.
SUBSTANCE: each of the methods involves separate step-by-step addition of vinyl chloride monomer during suspension polymerisation when degree of polymerisation conversion reaches 30-70%. The polymerisation method is a suspension polymerisation method which is carried out in the presence of an auxiliary protective colloid or polymerisation initiator.
EFFECT: obtained polyvinyl chloride has excellent processing properties and high packed density.
