Disclosed is a graft copolymer resin prepared by graft polymerizing a vinyl compound onto a composite-structured acrylic rubber whose particles are composed of a core consisting of a diene rubber enlarged by treatment with an acid group-containing copolymer latex, and an outer layer consisting of an acrylate polymer having a crosslinked structure formed by the combined use of a graft-linking agent and a cross-linking agent. This graft copolymer resin may be blended with a rigid thermoplastic resin in a specific proportion. This resin composition imparts a good gloss to the molded articles formed therefrom, while retaining excellent impact resistance and weather resistance.

Thermoplastic resin compositions having excellent impact resistance,

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.

A process for continuously casting a sheet and the like, comprising, running two feed belts positioned in face-to-face relationship to each other, opposed belt surfaces of said belts being in the same direction without relatively displacement; running at least two gaskets together with the two belt surfaces at the both edges thereof; maintaining the opposed surfaces in any position rigid in the direction perpendicular to the running one and flexible in the running direction; supplying material between the belts from one side thereof; supporting the opposed belt surfaces by pressure of the material and retaining a gap in desired thicknesses between the belt surfaces in desired positions thereof; treating continuously the material between the belt surfaces and delivering treated sheet from the other side of the belts.
