Abstract
PURPOSE: A molded produce that is obtainee by using the titled composition composed of an ethylene polymer or copolymer thereof with an α-olefin having a specific powder properties to effect the powder molding to cause the polyethylene to crosslink, thus having improved heat distortion, stress-crack resistance and oil resistance.
CONSTITUTION: The objective composition comprises (A) a powder of polyethylene or a copolymer thereof with an α-olefin that is prepared by suspension or gas-phase polymerization and has following characteristics: density, 0.915W 0.975g/cm3; MI, 5W80g/10min; the MI ratio of the low load (2.16kg) to the high load (21.6kg), less than 30; bulk density, 0.30W0.50; the repose angle, 25W40°; 50% particle size in the particle distribution, 230W350μ, more than 90wt% of the total, 149W500μ; the shape of the powder particles, sphere to ellipsoid, (B) 0.1W5PHR of dialkylperoxide of formulaI, II (n is 1, 2; R is tertiary alkyl; R', R" are alkyl) and (C) 0.5W10PHR of a crosslinking assistant such as triallylcyanurate.
