Zusammenfassung:	PURPOSE:To improve processability, dimensional stability, resistance to heat distortion and impact, etc., by blending a styrene/butadiene block copolymer, an ethylene/propylene block copolymer and glass fiber. CONSTITUTION:100pts.wt. first block copolymer obtd. by block-copolymerizing styrene (at least 65wt%) and butadiene and hydrogenating the resulting block copolymer, 60-150pts.wt. second block copolymer composed of a block copolymer of ethylene (5-9wt%) with propylene, and 20-50pts.wt. glass fiber are blended together. Said block copolymer has a melt flow index of 0.06-5/10min and is represented by the formula (wherein A is styrene block; B is butadiene block; n is an integer of 1-5). Said block copolymer has a melt flow index of 40-60g/10min and contains 17-23wt% xylene solubles at room temp. Glass fiber has an average diameter of 10-15mu and an average length of 200-300mu and is composed of at least 10vol% fibers having a length of 1,000mu or above.
