ROTATIONAL MOLDED ARTICLE FORMED FROM HIGH MOLECULAR WEIGHT POLYAMIDES

摘要

The invention relates to an article formed by a rotational molding process, having at least one layer formed from a high molecular weight polyamide. The high molecular weight polyamide is one having a molecular weight in the range of 20,000 to 35,000 and also having an inherent viscosity of 1.05-1.60 dL/g. Rotomolded articles having a high molecular weight polyamide layer have better low-temperature impact performance compared to articles formed from lower molecular weight polyamides.
