摘要： The present invention provides a method of preparing an aromatic vinyl-unsaturated nitrile-based copolymer in which, when an aromatic vinyl-unsaturated nitrile-based copolymer in which a content of a structural unit derived from unsaturated nitrile monomers in the copolymer is in the range of 22 to 30 wt % is prepared, oligomer content and unreacted monomer content are decreased, resulting in excellent heat resistance, significantly improved surface quality, and particularly, reduced generation of residue on a product surface when used in a closed high temperature environment and reduced occurrence of mold deposits during injection molding, and an aromatic vinyl-unsaturated nitrile-based copolymer prepared using the method.

摘要： The present invention relates to a modacrylic copolymer composition comprising acrylonitrile, vinylidene chloride, vinyl acetate, and at least one ionic comonomer. In one embodiment, the modacrylic copolymer composition comprises from about 45 to about 60% acrylonitrile, from about 35 to about 50% vinylidene chloride, from about 0.5 to about 5% vinyl acetate, and up to about 2% of a salt of p-sulfophenyl methallyl ether by weight of the total composition. The copolymer composition of the present invention provides acceptable color while having acceptable flame resistance.
