A long molded article having a skin layer composed of a thermoplastic elastomer, and a core layer coated with said skin layer which is composed of 30 to 70% by weight of a matrix phase composed of a polypropylene resin and 70 to 30% by weight of one dispersed phase selected from the group consisting of ethylene-.alpha.-olefin copolymers and styrene-based thermoplastic elastomers. According to the present invention, there can be obtained a long molded article such as a side molding for automobile, which is excellent in attractiveness after mounting, dimensional stability, etc.

Long sandwich molded article

A glass fiber reinforced resin composition is prepared, the composition consisting essentially of:

Glass fiber reinforced resin composition and wheel cap formed of same

A molded product of a polypropylene composition comprising 60 to 85% by weight of a polymer mixture, 2 to 10% by weight of a fibrous filler, and 5 to 38% by weight of an extender. The polymer mixture comprises 30 to 70 parts by weight of polypropylene and 30 to 70 parts by weight of a copolymer of ethylene and an alpha-olefin having a Mooney viscosity [ML.sub.1+4 (100.degree. C.)] which is lower than 70 out of a total of 100 parts of polypropylene and copolymer. The copolymer forms particles dispersed in the product, and the particles have an aspect ratio of at least 5.

Molded polypropylene-.alpha.-olefin product having low coefficient of

A fiber-reinforced polypropylene resin composition is disclosed, comprising (1) a mixed polymer of polypropylene and carboxyl group containing polypropylene, (2) a silane treated reinforcing fiber, and (3) a coloring component of zinc sulfide and carbon black with a dispersing agent compounded thereto, said dispersing agent is polyethylene wax and the amount of said dispersing agent added to 20 to 50 parts by weight per 100 parts by weight of the zinc sulfide and carbon black.

Fiber-reinforced polypropylene resin composition

There is provided a thermoplastic olefin elastomer of polyblend composed of 30 to 70 wt % of ethylene-propylene-diene terpolymer (EPDM), 10 to 30 wt % of ethylene-vinyl acetate copolymer (EVA), and 20 to 50 wt % of polypropylene (PP). The EPDM is specified by the Mooney viscosity, propylene content, and third component. The EVA is specified by the VA content and number-average molecular weight. The PP is specified by the number-average molecular weight. This elastomer is suitable for use as a raw material for automotive exterior trim such as side molding, bumper, and mud guard which are produced by injection molding. The elastomer also affords molded items having a good matte-finished appearance. The polyblend obviates the process for partial crosslinking which was necessary for the preparation of conventional elastomer for injection molding.
