Abstract

1469396 Heat-stabilized polyamides RHONEPOULENC INDUSTRIES 12 Feb 1976 [14 Feb 1975] 05604/76 Heading C3R Polyamides are heat stabilized by incorporating therein (a) 0À04 to 3% (by weight) of an alkali or alkaline earth metal halide, (b) 0À001 to 2% Cu as a complexed or non-complexed organic or inorganic salt and (c) 0À1 to 5% of a C 3-20 glycol with the OH groups in the alpha and gamma positions. The polyamide may also contain other conventional adjuvants such as fillers, lubricants, other stabilizers, plasticizers, pigments, dyes or crystallization agents, e.g. glass or asbestos fibres, glass microspheres, talc, silica and mica. Various polyamides and additives (a), (b) and (c) are mentioned; in specific examples the polyamide is nylon 66 and (a) is KI, (b) is copper stearate or cuprous oxide and (c) is 2,2-dimethyl-1,3-propanediol or 2-ethyl- 1,3-hexanediol. In the examples the glycol is melted, the copper salt and KI of particle size below 100 microns are added to the melt and stirred and the mass is cooled and ground to flakes of size less than 6 mm. which are then mixed and homogenized with the nylon.
