Abstract:
An improved polyamide resin composition for weldable moulded articles which comprises:(a) 99.9-30% by weight of a polyamide-containing compound;(b) 0.1-20% by weight of a plasticising compound selected from the group consisting of esters of low molecular weight poly(ethylene glycol) having the formula (I)R--COO--(CH.sub.2 CH.sub.2 O).sub.n --OC--R (I)wherein R is a branched or straight chain alkyl group having from 1 to 40 carbon atoms, and n is 2 to 20; or a long chain alkyl polyester of formula (II)HOOC--R--CO--(O--R'--O--CO--R--CO).sub.n --O--R'--OH (II)wherein R is alkyl of 16 to 45 carbon atoms, R' is alkyl of 2 to 6 carbon atoms, or, wherein R is an alkyl of 2 to 6 carbon atoms, R' is an alkyl of 16 to 45 carbon atoms, and n is 2 to 50, and(c) the balance of the composition up to 100% being selected from one or more additive compounds.
