    摘要： A composition for making an elongated molded product which can be satisfactorily used without having to be painted. The composition comprises an elastomer comprising crystalline polypropylene and ethylene-.alpha.-olefin rubber (EOR), and 0 to 15 phr of talc. The polypropylene (PP) and EOR have a blending ratio (PP/EOR) by weight of 35/65 to 67/33. The polypropylene has a Q value (M.sub.w /M.sub.n).gtoreq.10 and a melt flow rate of 50 to 120. The EOR has an .alpha.-olefin content of 10 to 20% by weight. The proportion Y of talc and the proportion X of the EOR in the elastomer satisfy the relation: Y.gtoreq.-0.63X+34.

    摘要： A damping resin composition contains: 100 parts by weight of a polymer blend of 40 to 70% by weight of a polypropylene resin and 30 to 60% by weight of a thermoplastic elastomer; and 5 to 60 parts by weight of an inorganic filler, the thermoplastic elastomer comprising at least one member selected from the group consisting of an elastomer having a Tg of 0° C. to 20° C. and an elastomer having a Tg of −20° C. to 0° C. and an ethylene-&agr;-olefin copolymer. Using this damping resin compostion, a vehicle rocker-panel molding, which is attached to the lower part of a vehicle side body is molded. The rocker-panel molding has a bottom section and a side section substantially perpendicular to the bottom section and having prescribed rigidity, showing a nearly L-shaped crosswise profile, in which the bottom section is thinner than the side section so that vibration energy generated on foreign matter's striking against the rocker-panel molding is forcibly converted to heat energy by the thinner bottom section thereby to suppress transmission of noise to the space of the automobile.

    摘要： A process for dimensionally stabilizing an article molded from a synthetic resin material, such as PVC. The molded article is subjected to a first cooling treatment to cool the article at a temperature lower than the glass transition temperature Tg of the synthetic resin followed by a heating treatment at a temperature higher than the glass transition temperature Tg and then is subjected to a second cooling treatment again at a temperature lower than the glass transition temperature Tg. Following such treatment steps, the molded article, such as side molding for automobiles, have less variation in dimensions and less shrinkage after molding in use.
