<p>A blend is made of, by weight (a) 10-70 parts of a polyphenylene ether which may have various substituents on the phenyl nucleus, and has at least 50 recurring units, (b) 30-90 parts of a polyamide (a nylon) and optionally (c) 3-50% of a rubbery polymer which is elastic at room temperature (e.g. a copolymer of an aromatic vinyl compound and a conjugated diene); and as a stabilizer, a thioether compound (preferably of formula R<0>-S-CHR<1>R<2>, where the Rs are hydrocarbon or substituted hydrocarbon groups of 1-35 C atoms and R<1> and R<2> can be H; 28 specific compounds are shown. Optional further ingredients are 0.01-5 parts of sterically hindered phenol compound; and 0.01 to 30 parts of a compound containing a -C=C- or -C=C- bond and a polar group (e.g. carboxyl group), per 100 parts of (a), (b) and (c). The blending can be at 200-380 DEG C, and the melt is extruded and pelletised. The resultant resin composition can be molded into products of large size, e.g. for automobile parts, and is highly resistant to solvents.</p> |
