The present invention provides a carboxyl group-containing copolymer having a better calcium ion trapping ability and a better carbon black dispersing ability than any conventional carboxyl group-containing copolymers. The present invention relates to a carboxyl group-containing copolymer including a structural unit (a) derived from an unsaturated monocarboxylic acid monomer (A), a structural unit (b) derived from an unsaturated dicarboxylic acid monomer (B), and a structural unit (c) derived from a cationic monomer (C).

A rubber modified vinyl-based graft copolymer of the present invention has a core-shell structure in which a shell is formed by graft-polymerizing a monomer mixture to a core comprising a rubbery polymer, wherein the monomer mixture comprises: an aromatic monomer comprising an -substituted aromatic vinyl-based monomer represented by chemical formula 1 and an aromatic vinyl-based monomer excluding the -substituted aromatic vinyl-based monomer; a cyanovinyl-based monomer; and a maleimide-based monomer. A thermoplastic resin composition containing the rubber modified vinyl-based graft copolymer has excellent impact resistance, heat resistance, appearance characteristics and the like.

A copolymer is capable of being immobilized on a base material while maintaining a high antithrombotic property persistently without having to introduce heparin or an anticoagulant drug to the surface thereof. The copolymer includes monomer unit A, monomer unit B, and monomer unit C, wherein monomer unit C has a mole fraction of 0.5-40% with respect to the total amount of all constituent monomer units.

What are described are copolymers formed from (a) at least one monomer M1 of the formula ##STR00001##
in which R.sup.1 is an organic radical having a (meth)acryloyl group, R.sup.2, R.sup.3 and R.sup.4 are each independently a hydrogen atom or a C1- to C10-alkyl group; and (b) at least one ethylenically unsaturated, free-radically copolymerizable monomer M2 other than the monomers M1. What are also described are two-pack adhesives comprising the copolymers and a polyfunctional hardener. The copolymers and the two-pack adhesives can be used as laminating adhesives.
