Abstract

PURPOSE: To obtain PVC with excellent heat stability, shortening the polymerization cycle, by the supension polymerization of vinyl chloride in the prence of both α,α- dimethylbenzyl proxyneodecanoate and another specified oil-soluble polymerization initiator.
CONSTITUTION: (A) 100pts.wt. monomer (mixture) consisting of (i) vinyl chloride and, if necessary, of (ii) another vinyl monomer, are suspension-polymerized at 20W75°C in the presence of (B) 0.001W0.5pst.wt. α,α-dimethylbenzyl peroxyneodecanoate and (C) 1/4W4 times as much as the component (B), of an oil-soluble polymerization initiator (e.g., dilauroyl peroxide) of half-life period of 10hr at 20W 65°C in a 0.2mol solution of trichloroechylene, to obtain the titled polymer.
EFFECT: The initial reaction is more moderate as compared with that when another low temperature-active initiator is used, so that the polymerizer is easily cooled.
