摘要:
The cycloolefin resin compositions of the present invention comprise:[A] cycloolefin resin selected from (a-1) a cycloolefin random copolymer having recurring units derived from a cycloolefin of a specific structure, (a-2) a ring opening (co)polymer of the cycloolefin, (a-3) a hydrogenation product of the ring opening (co)polymer and (a-4) a graft-modified product of the random copolymer (a-1), the ring opening (co)polymer (a-2) and the hydrogenation product thereof (a-3);[B] at least one of (b-1) an unmodified elastomer, (b-2) a modified elastomer, (b-3) an unmodified crystalline polyolefin and (b-4) a modified crystalline polyolefin; and[C] a polyamide resin. Molded products formed from these cycloolefin resin compositions are excellent particularly in resistance to greases.
