RESIN COMPOSITE MATERIAL

PROBLEM TO BE SOLVED: To obtain a resin composite material with a favorable balance between modulus of elasticity and elongation without marked decline of the elongations and impact resistance even in filler rich compositions. SOLUTION: This resin composite material is composed of 90-5 pts.wt. polyp...

Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a resin composite material with a favorable balance between modulus of elasticity and elongation without marked decline of the elongations and impact resistance even in filler rich compositions. SOLUTION: This resin composite material is composed of 90-5 pts.wt. polypropylene, 90-5 pts.wt. 1-butene polymer satisfying conditions of (1) melting point (Tm-D) of 0-100C° defined by differential scanning calorimeter (DSC), (2) 20 or less of steric regulatory index ä(mmmm)/(mmrr+rmmr)}, (3) molecular wt. distribution (Mw/Mn) of 4.0 or less determined by gel permeation chromatography (GPC) and (4) wt.-average molecular wt. (Mw) of 10,000-1,000,000 determined by GPC, and 5-90 pts.wt. organic filler and/or inorganic filler. COPYRIGHT: (C)2003,JPO
