METHOD OF INTENSIFICATION OF SUSPENSION VINYL CHLORIDE POLYMERIZATION Russian patent published in 1998 - IPC

Abstract RU 2109755 C1

FIELD: chemical technology. SUBSTANCE: method involves the use of protective colloid and initiating system based on an aqueous and monomer-soluble initiating agent. The latter is di-2-ethylhexylperoxydicarbonate. Alkaline metal or ammonium persulfate is used as a water-soluble initiating agent that is added to reaction mixture before polymerization onset at amount 0.005-0.02% of monomer mass being simultaneously with monomer-soluble initiating agent. EFFECT: improved method of intensification. 1 tbl
