    Abstract: A polypropylene composition comprising 95 - 55 parts by weight of polypropylene (A) and 5 - 45 parts by weight of an ethylene/1-butene random copolymer (B-1) which contains constituent units derived from 1-butene in an amount of 15 to 25 % by mol; and a polypropylene composition comprising 95 - 55 parts by weight of polypropylene (A) and 5 - 45 parts by weight of an ethylene/1-octene random copolymer (B-2) which contains constituent units derived from 1-octene in an amount of 8 to 20 % by mol. Each of the random copolymers (B-1) and (B-2) has an intrinsic viscosity [ eta ] of 1.5 to 3.5 dl/g as measured in decalin, a glass transition temperature (Tg) of not higher than -50 DEG C, a crystallinity of less than 20 % as measured by X-ray diffractometry, a randomness parameter (B value) of 1.0 to 1.4 as measured by C-NMR spectroscopy. With respect to a melting point as measured by a differential scanning calorimeter (DSC) as the main peak, the copolymer (B-1) has a value of not higher than 60 DEG C, while the copolymer (B-2) has a value of not higher than 80 DEG C.

    Abstract: Polyolefin resin compositions having a sea and island structure wherein cycloolefin resin, graft modified cycloolefin resin and graft modified elastomer components are finely dispersed in polyamide by melt kneading the cycloolefin resin, graft modified cycloolefin resin, graft modified elastomer and polyamide. Molded products formed by using the polyolefin resin compositions of the present invention are high in impact strength and surface characteristics, particularly less in surface delamination, and also excellent in surface glossiness. The molded products are low in water absorption properties and also excellent in oil resistance.
