PURPOSE:To provide the titled compsn. having excellent dimensional accuracy and resistance to oils and heat, by blending a reinforcing agent with a thermo plastic resin mixture of an arom. polyphenylene ether resin, etc. and a polyethy lene terephthalate resin. CONSTITUTION:5-150pts.wt. reinforcing agent (e.g. glass fiber or silica) is blended with 100pts.wt. thermoplastic resin mixture of 20-80t% arom. polyphenylene resin (A) composed of a structural unit of formula I (wherein R1, R2 are a sterically non-hindering 1-4C alkyl, aryl, halogen, H) or said unit of formula I and a structural unit of formula II (wherein R<3>-R<6> are each R<1>; one of R<5> and R<6> is always a group other than H) or copolymer thereof, or mixture thereof with a styrene resin such as a polymer obtd. from an arom. nonovinyl monomer of formula III (wherein R is lower alkyl, halogen; Z is R, H; p is 1-5) and 80-20wt% polyethylene terephthalate resin (B) having a crystal m.p. of 255-265 deg.C and an intrinsic viscosity of 0.2dl/g (in o- chlorophenol at 25-30 deg.C) represented by formula IV. |
