CONTINUOUS DOSING EXCLUSIVELY RAPIDLY ACTING INITIATING AGENTS DURING POLYMERIZATION REACTION Russian patent published in 2006 - IPC C08F14/06 C08F114/06 C08F4/32 C08F4/38 

FIELD: chemistry of polymers, chemical technology.

SUBSTANCE: invention relates to a polymerization method of vinyl chloride monomer and optionally additional monomers by using a single or some organic peroxides. This method involves dosing at least one organic peroxide compound with half-time value from 0.0001 h to less 0.050 h at the polymerization point to the polymerization mixture. Dosing such initiating agent allows achievement of improving the polymerization rate regulation and higher rate of polymerization. By using this method vinyl chloride-base (co)polymer is prepared having less 50 mass parts of residual initiating agent per one million of mass parts of (co)polymer in measuring after polymerization and drying (co)polymer at 60°C for 1 h directly. (Co)polymer can be used in the molding process involving heating a (co)polymer to temperature exceeding its boiling point.

EFFECT: improved method for polymerization.
