Vinyl chloride resin-based composition for floppy disc jacket

摘要

The invention provides a formulation of a vinyl chloride resin-based composition suitable for preparing floppy disc jackets having high heat resistance with a Clash-Berg temperature of 75 DEG C. or higher comprising, as the essential components, (A) a copolymer of viny chloride with a N-substituted maleimide as the comonomer, optionally in combination with a homopolymeric polyvinyl chloride resin, (B) an impact-strength improving agent which is preferably a vulcanizable synthetic rubber and (C) carbon black.
