  • Rotational molding of articles having impact resistance
    Patent number: 4970045
    Abstract: The present invention is a method of rotationally molding an article having a layer made of polyamide composition. The method comprises the steps of melt blending a polyamide composition comprising the polyamide and a copolymer comprising units derived from an alpha-olefin of the formula RCH.dbd.CH.sub.2 where R is H or an alkyl having from 1 to 8 carbon atoms and from 0.2 to 25 mole percent based on the alpha-olefin-acid copolymer of an alpha, beta-ethylenically unsaturated carboxylic acid having from 3 to 8 carbon atoms. The copolymer has from 10% to 90% of the carboxylic groups neutralized by metal ions. The melt blended composition is formed into particles, including pellets and powder, suitable for rotational molding. The particles are rotationally molded to form an article.

  • Nylon composition for use in rotational molding
    Patent number: 4729862
    Abstract: A rotational moldable polyamide composition, a method of preparing the composition, and a method of rotational molding. The composition contains from about 0.001 percent to about 0.5 percent by weight of a copper compound, preferably cuprous iodide. Preferably, the composition contains from about 0.001 percent to about 0.3 percent by weight of potassium iodide.
