<p>PROBLEM TO BE SOLVED: To obtain the subject composition improved in such problems as to decline in its mechanical properties and develop resin waste deposition during its continuous molding operation for a long time when incorporated with a large amount of filler for the purpose of improving its dimensional stability, rigidity, heat resistance or ready combustibility. SOLUTION: This composition is obtained by blending (A) 100 pts.wt. of an ethylene-α-olefin copolymer with (B) 10-400 pts.wt. of a filler and (C) 0.1-10 pts.wt. of a resin waste deposition-proofing agent. The ethylene-α-olefin copolymer is prepared by copolymerization between ethylene and a 3-20Cα-olefin in the presence of a catalyst containing at least one kind of group IV transition metal compound containing a cyclopentadienyl skeleton-bearing ligand, and has the following characteristics: density is 0.86-0.96g/cm<3> , melt flow rate is 0.01-50g/10min, molecular weight distribution Mw /Mn is 1.5-5.0, and composition distribution parameter Cb is 1.01-1.2.</p> |
