PURPOSE:To provide the titled compsn. which retains excellent mechanical strengths even after it is brought into contact with an anti-freeze in a radiator tank over a long period of time, by blending an olefin polymer with glass fiber bundled by using an acrylic resin. CONSTITUTION:100pts.wt. mixture of an olefin polymer (A) which is a crystalline polymer having an intrinsic viscosity of 0.3-15dl/g (in decalin solvent at 135 deg.C) and a m.p. of pref. 140 deg.C or higher (ASTM D3418) (e.g., a propylene homopolymer) and optionally a polyamide (B) (e.g., nylon 6) is blended with 5-200pts.wt. glass fiber (C) (e.g., glass roving) bundled by using an acrylic resin (e.g., a methyl acrylate resin). If desired, an antioxidant, a lubricant, a flame retarder, a pigment, a filler, etc., are added thereto.
