摘要
A poly(phthalazinone sulfone) composition for molded articles having such characteristics as high temperature resistance, good electrical properties, good chemical and solvent resistance and toughness consists essentially of a polymer of formula (I):Cp-ZxA-Zy (I)wherein Z is a bisphenyl sulfone moiety of formula: (II):; A is a phthalazinone moiety of formula (III):; Cp is A, as defined above, or a biphenol moiety of formula (IV):; x is an integer of at least 1;y is an integer of at least 1; and x+y=n, where n is an integer such that the polymer has a weight average molecular weight of about 20,000 to about 170,000, the composition comprising less than 5%, by weight, of low molecular weight oligomers; and having a glass transition temperature (Tg) from 225 to 305° C.
