摘要

A thermoplastic resin (T) comprises: (A) 1-99 wt.% of polyphenylene ether; and (B) 99-1 wt.% of one or more non-crystalline thermoplastic chosen from alkenyl aromatic resins, non-crystalline aromatic polyesters, methacrylates, polyetherimides or aromatic polysulphones. (T) contains 0.001-15 pts. wt. of at least one 4-amino-2,2,6,6-tetramethylpiperidyl cpd. (C) of formula (1) or (2), per 100 pts. (A) and (B). In the formulae, R1 = H, O, OH, (cyclo)alkyl, allyl, benzyl, aryl, alkanoyl, alkenoyl or (cyclo)alkyloxy; R2 = H, alkyl or gp. of formula -R4C(=O)-(-X-)-R5 (3); R3 = n-valent organic gp.; R4 = single bond, alkylene, alkylidene or arylene; R5 = H, alkyl, aryl or gp. of formula -CH=CHC(=O)OH (4) or (5); X = single bond, O or NH; n = 1 - 4; and p = 2 - 6.
