A maleimide-based copolymer containing maleimide monomer units (a-1), aromatic vinyl monomer units (a-2) and other vinyl monomer units (a-3), wherein,

Maleimide-based copolymer and resin composition comprising the same

Disclosed is a thermoplastic resin composition comprising a graft polymer resin (I) obtained by polymerizing one or more monomers (b) selected from the group consisting of aromatic vinyl compounds and ethylenically unsaturated compounds, in the presence of a latex of an ethylene-propylene-non-conjugated diene terpolymer rubber (a) having a specific gel content and a specific particle diameter, so that the graft polymer resin contains a specific proportion of the rubber (a); and a rigid thermoplastic resin (II). This resin composition has excellent weather resistance and impact resistance, and yields molded articles having a good surface gloss.

Thermoplastic resin composition of ethylene-propylene-non-conjugated

An intermediate for a composite material is disclosed. The intermediate is obtained by impregnating an epoxy resin composition containing a specific additive into a carbon fiber. The composite material obtained from the intermediate has improved mechanical properties.

Intermediate for composite materials

A polyolefin resin composition comprising a polyolefin modified with an unsaturated carboxylic acid, at least one member selected from the group consisting of polyepoxides, polyisocyanates, and polyamines, and a reinforcement.

Composite material with improved properties

A polyolefin resin composition comprising a modified polyolefin prepared by reacting a polyolefin with an unsaturated carboxylic acid in the presence of a catalyst including at least one member selected from the group consisting of ketal peroxides and dialkyl peroxides having a decomposition temperature necessary for attaining the half life of 10 hours of at least 80.degree. C., and a fibrous, powdery, or flaky reinforcement.
