FIELD: chemistry.
SUBSTANCE: invention refers to polymerisation process wherein, at least, one peroxide of half-period 1 to 0.001 h at polymerisation temperature the moment being added, is dosed to the reaction mixture at polymerisation temperature and wherein, at least, during a part of peroxide dosage period i) a coolant unit of a reactor is exposed essentially to maximum cooling ability and ii) mount or initiator added is actively regulated by a temperature controller, thus ensuring polymerisation temperature to be maintained within 0.3°C or lower than specified desirable polymerisation temperature.
EFFECT: improved reproducibility of polymers.
