FIELD: chemistry of polymers. SUBSTANCE: method involves styrene polymerization at 84-110 C in aqueous suspension in the presence of radical initiating agent and molecular mass regulating agent. Regulating agent of molecular mass: mixture of three isomers: 2,4-diphenyl -4-methylpentene -1, 2,4-diphenyl -4-methylpentene-2 and 1,1,3-trimethylphenylindane at concentration 1-3% of monomer mass. Mass ratio of regulating and initiating agents is maintained at the level (0.67-1.5):1. EFFECT: improved method of synthesis. 1 tbl
