POLYMERISATION METHOD WITH HIGH OUTPUT USING SPECIAL INITIATING SYSTEM Russian patent published in 2009 - IPC C08F4/38 C08F14/06 C08F114/06 

FIELD: chemistry.

SUBSTANCE: proposed here is a polymerisation method of one or more monomers using at most, 90 wt % safe amount of a first initiator. The safe amount of initiator used is the maximum amount of the given initiator, which can be used in an identical method, realised at maximum cooling power, and temperature of which does not exceed a set temperature value. A second initiator is used, with half-life from 0.0001 to 1.0 hours at polymerisation temperature. The second initiator has less thermal stability than the first initiator. 10% monomer(s) are at least partially added before polymerisation, in such a quantity and preferably at a different rate such that, not less than 92% of the maximum cooling power is used, at least, in the period of time, in which not less than 10 wt % monomer is polymerised. The initiators are chosen from organic peroxides and standard azo-initiators.

EFFECT: cheap method of producing polymers, particularly polymers containing polymerised vinylchloride.
