METHOD FOR RADICAL POLYMERISATION OF ETHYLENE UNSATURATED COMPOUNDS Russian patent published in 2010 - IPC C08F2/04 C08F4/04 C08F4/32 C08F220/10 C08F218/14 

Abstract RU 2401280 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method for radical polymerisation of one or more ethylene unsaturated compounds of formula (II), characterised by that at least one radical polymerisation initiator is added in at least two steps to ethylene unsaturated compounds taken in amount of at least 80.0% of the total weight of ethylene unsaturated compounds. More polymerisation initiator is added at the second step than at the first step. The polymerisation initiator at the first and second step is added gradually and the ratio of average rate of adding at the second step to the average rate of adding at the first step is greater than 1.2:1.

EFFECT: improved method.
