PURPOSE: To obtain the title composition with improved crosslinking effect, capable of intimately bonding to metals when melted leading to prevention of crater development, by incorporating polyethylene with a rubber, a crosslinking agent, and a crosslinking auxiliary such as 1,2-polybutadiene. n CONSTITUTION: The objective composition can be obtained by incorporating (A) 100 parts by wt. of polyethylene, with (B) 5W50 parts by wr. of a rubber, (C) a crosslinking agent, and (D) 0.5W5wt. times, based on the wt. of the component (C), of one or more of crosslinking auxiliaries selected from 1,2-polybutadiene, triallyl cyanurate, and triallyl isocyanurate. Said crosslinking agent is, e.g., a bis (tertiary alkylperoxy) alkane of formula I (n is 1 or 2; R is tertiary alkyl residue; R' and R" are each hydrocarbon residue, or alkylene residue linked to form cycloalkylene residue) or a bis(tertiary alkylperoxy) banzene of formula II. n COPYRIGHT: (C)1980,JPO&Japio |
