Title:
VLNYL CHLORIDE RESIN COMPOSITION
Document Type and Number:
Japanese Patent JPS57117554
Kind Code:
A
Abstract:
PURPOSE: A non-rigid polymer composition useful as electric wires in apparatus of computers, haveing low aging properties under heating, and improved heat resistance, obtained by subjecting vinyl chloride resin with a specific alkyl(meth) acrylate and acrylonitrile to graft copolymerization.
CONSTITUTION: 100pts.wt. vinyl chloride resin, preferably resin having a degree of polymerization of 500W5,000 by suspension polymerization, is subjected to graft polymerzation (advantageously radical polymerization) with 35W90pts.wt. alkyl(meth)acrylate having a second-order transition point of ≤-10°C in the presence of 2W50pts.wt. acrylonitrile preferably at 30W100°C for 1W10hr in an inert gas atmosphere containing no oxygen.
