ABSTRACT:
A process for the fabrication of a polyamide article is disclosed, in which a composition of a linear aliphatic polyamide, 0.01-5% by weight of an epoxide and 0.005-1.0% by weight of a catalyst selected from catalysts of the type used in the polymerization of polyamides and epoxide ring-opening compounds is admixed in a manner that provides an effectively uniform admixture and extruded. The epoxide compounds have at least two terminal epoxy groups and a molecular weight of less than 1000. A preferred catalyst is sodium hypophosphite. Increases in melt viscosity of the polyamide in excess of four-fold may be obtained. The compositions may be used in the formation of film by a blown film process, the blow moulding of bottles, thermoforming processes or the like.
