VINYL CHLORIDE-BASED COPOLYMER AND RESIN COMPOSITION FOR MAGNETIC RECORDING

摘要

PROBLEM TO BE SOLVED: To obtain both a vinyl chloride-based copolymer capable of improving dispersibility of magnetic powder by possession of high reactivity, providing adhesiveness and adding functions such as endowment of reactivity with a functional group and a resin composition for magnetic recording using the vinyl chloride-based copolymer. SOLUTION: This vinyl chloride-based copolymer characteristically comprises vinyl chloride and anα-(hydroxymethyl)acrylic acid alkyl ester of the formula CH2 =C(CH2 OH)COOR (R is a 1-4C alkyl group). The resin composition for magnetic recording comprises the vinyl chloride-based copolymer.
