Abstract

PURPOSE: The titled elastomer excellent in moldability, strength, etc., prepared by adding a peroxide-crosslinkable low-MW ethylene/α-olefin copolymer oligomer and a polyolefin resin to a partially crosslinked product of a peroxide-crosslinkable high-MW ethylene/α-olefin copolymer rubber.
CONSTITUTION: To (A) a partially crosslinked product of 100pts.wt. peroxidecrosslinkable high-MW ethylene/α-olefin copolymer rubber, Mooney viscosity about 40W170, prepared by copolymerizing ethylene with an α-olefin such as propylene or 1-butene is added (B) a partially crosslinked product of 10W70pts.wt. peroxidecrosslinkable low-MW ethylene/α-olefin copolymer oligomer, Mooney viscosity ≤about 5, as a moldability improver. Next, the resulting mixture is further mixed with (C) a polyolefin resin, e.g., polyethylene or polypropylene, in an amount to provide a component C/component A weight ratio of 10/90W90/10, to obtain the thermoplastic elastomer of the purpose.
