摘要:
A resin composition comprising (a) a polyphenylene ether resin, (b) a non-crystalline or low-crystalline polyamide resin, (c) a crystalline polyamide resin and, if desired, (d) a polar compound or a low-molecular diene bolymer or the component (d) and (e) a rubbery polymer or an alkenyl aromatic compound/conjugated diene copolymer or a hydrogeneration product thereof. The composition is excellent in both impact strength, barticularly on a plane part of a plate-molded article, and dimensional stability.
摘要:
A sheet of a polymer comprising at least 50 mol% of units of an olefin (e.g. polypropylene ) is coated on one surface with an aqueous solution or dispersion
(A) 55 to 90% of a polymer comprising an olefin; (B) 1 to 30% of a copolymer of ethylene and acrylic acid; and (C) 10 to 30% of a polymer containing styrene units.
The sheet optionally contains up to 65% of an inorganic fine powder. The adhesive layer adheres strongly to a cellular foamed polyurethane, to form a composite heat-insulating material without voids. The polymer sheet can be deep-drawn to shape, adhesive-coated, placed over the metal pressing of a refrigerator body or door, and the urethane components injected through a hole in the sheet so that the polyurethane is formed between the sheet and the metal pressing and is foamed and adhered in situ ; the sheet can be a laminate having a lustrous outer surface layer.
