Abstract

PURPOSE: To obtain the title composition improved in heat resistance, tensile strength, weathering resistance and balance between rigidity and impact resistance, etc., by dynamically heat-treating an ethylene/α-olefin copolymer rubber and a specified polyolefin resin in the presence of a crosslinking agent.
CONSTITUTION: A catalyst (b) is obtained by bringing a highly active titanium solid catalyst component (i) having Mg, Ti and a halogen as essential components, an organometallic compound catalyst component (ii) containing a Group I-III metal of the periodic table and an electrondonating catalyst component (iii) of which at least part may be contained in component (i) into contact with each other in the presence of an α-olefin at -50-100°C for 1min-10hr in an inert medium. An α-olefin (a) is polymerized at 20-200°C in the presence of component (b) under a normal pressure to 100kg/cm2 to obtain a polyolefin resin (B). 100 pts.wt. mixture of 100-10 pts.wt. ethylene/α-olefin copolymer rubber (A) of a Q value (weight-average MW/number-average MW according to gel permeation chromatography) of 2.5-8 with 0-30 pts.wt. component B is dynamically heat-treated in the presence of a crosslinking agent to obtain the title composition at least partially crosslinked.
