ABSTRACT:
Reinforced thermoplastic compositions are provided comprising a high molecular weight linear polyester, such as poly(1,4-butylene terephthalate) in combination with a reinforcing agent and a minor proportion of an alkylhydroxyphenylalkanoyl-hydrazine, such as N,N'-bis(3,5-di-tert-butyl-4-hydroxy-hydrocinnamoyl)-hydrazine. The use of the alkylhydroxyphenylalkanoyl-hydrazine retains the inherent resistance to high voltage breakdown of the polyester resin component while not affecting the other properties of the composition, such as strength, modulus, shrinkage, etc.
