PURPOSE:To provide the title compsn. having excellent dimensional stability and weather resistance under high-temperature conditions, by blending a crystalline propylene polymer with potassium titanate fibers and a hindered amine compd. or a benzoate compd. CONSTITUTION:The title compsn. consists of a crystalline propylene polymer (A), 30-1% (by weight; the same applies hereinbelow) potassium titanate fibers (B) having an average fiber diameter of 0.1-1.0mu and an average aspect ratio of not lower than 5, 0.01-1pt.wt. (based on the total amount of the components A, B, D and E) hindered amine compd. or benzoate compd. (C) of the formula (wherein X is a 2-18C alkylene; Y is a bivalent aliph., alicyclic, arom. or alkylated arom. group which may have a hetero atom such as O, N or P in its carbon chain or on its side chain; n is 2-100), 0-30% talc (D) having an average particle size of not larger than 5mu and 0-40% ethylene/propylene copolymer rubber (E) having a propylene content of 20-80% and a Mooney viscosity ML1+4 (100 deg.C) of 5-120, in which the amount of the component A is 40-99% when the components D and/or E are/is incorporated, or 70-99% when they are not incorporated. |
