Phonograph record compound

Abstract

PURPOSE: To prepare a compound having high moldability, and capable of producing phonograph records having excellent sound quality, stably in high efficiency, by compounding a vinyl chloride-vinyl acetate copolymer having low polymerization degree with a vinyl chloride resin having high polymerization degree. CONSTITUTION: The objective compound can be obtained by compounding a vinyl chloride-vinyl acetate copolymer having low polymerization degree (e.g. having an average polymerization degree of 400W600) with 10W25pts.wt. of a vinyl chloride resin having high polymerization degree (e.g. an average polymerization degree of 1,000W1,300).
