Abstract

1,265,383. Plasticized anionic copolylactams. E.I. DU PONT DE NEMOURS & CO. 5 March, 1969 [6 March, 1968], No. 11831/69. Heading C3R. Plasticized copolyamides are obtained by anionically copolymerizing, by weight of the total composition, 65 to 90% of coprolactam with at least 1% of one or more lactams containing 7 to 12 C atoms in the lactam ring in the presence of 2 to 20% of an N-alkyl pyrrolidone as plasticizer. The specified proportion of this plasticizer is stated to give outstanding resistance to damage by impact, rendering the copolymer particularly suitable for tenpin skittles. Polymerization may be effected directly in the mould using a conventional catalyst and accelerator and optionally a thickening agent, pigment filler, antioxidant, blowing agent or mould release agent, e.g. a soluble polyamide, a polycarbonate, alkali stearate, benzene, heptane, propane, TiO 2 or allylic azides and diazirines.
