Abstract

1,144,213. Vinyl-2-oxazolidone polymerization. FERRANIA S.p.A. 16 June, 1966 [16 June, 1965], No. 27020/66. Heading C3P. [Also in Division G2] Polv-N-vinyl-2-oxazolidone is prepared by polymerizing N-vinyl-2-oxazolidone in dimethyl formamide with a 2,2<SP>1</SP>-azo-bis-isobutyronitrile. Copolymers with vinyl acetate or acrylamide of N-vinyl-2-oxazolidone are prepared using the same catalyst.
