Abstract: PURPOSE:To improve shape stability and impact resistance, by blending an ethylene copolymer having a specified copolymer composition and glass bead pretreated with epoxysilane, with a thermoplastic polyester. CONSTITUTION:1-30pts.wt. ethylene/glycidyl methacylate copolymer contg. 3-9wt% copolymerized glycidyl methacrylate and 7-150pts.wt. glass bead pretreated with epoxysilane, are blended with 100pts.wt. thermoplastic polyester such as polyethylene terephthalate or polyethylene naphthalate to produce the desired polyester compsn. for molding. The pretreatment of glass bead is conducted in such a manner that a soln. of epoxysilane is mixed with glass bead with stirring, and the mixture is left to stand in order to precipitate glass bead which is then separated and dried.

Abstract: PURPOSE:To produce a molding resin compsn. excellent in the low-temp. impact strength, heat resistance, etc., by melt mixing an aliph. polyamide, a polyphenylene ether, a specific diene block copolymer, and an alpha,beta-unsatd. carboxylic acid in a specific way. CONSTITUTION:A polyphenylene ether is melt mixed with an alpha,beta-unsatd. carboxylic acid (e.g. maleic anhydride) and then with 5-95wt.% aliph. polyamide (e.g. nylon 6) and a diene block copolymer selected from the group consisting of an A-B-A' type block copolymer elastomer (wherein A and A' are each an arom. hydrocarbon polymer block; and B is a conjugated diene polymer block) and a hydrogenated A-B-A' type block copolymer elastomer (wherein the internal polymer block B is hydrogenated). The resulting mixture is further melt mixed with the rest, 95-5wt.% of the polyamide, thus producing a molding resin compsn.
