Abstract

1304654 Polymerizing vinyl chloride SHINETSU CHEMICAL CO 30 April 1971 [4 May 1970] 12556/71 Heading C3P In the suspension polymerization of vinyl chloride in a vessel provided with a condenser, the monomer, water and suspending or dispersing agent are first stirred and only after bubbling has ceased the initiator is added. Preferably the condenser is operated only after polymerization has commenced and an alkaline substance, organic amine, oxidizing agent or nigrosine dye is added to the polymerization medium.
