Abstract:
1. A melt processable copoly(phthalazinone ether sulfone) composition of formula 1, consisting essentially of: wherein a, b, c, and d represent mole fractions of the monomers present in the copolymer, wherein each are independently from 0.1 to 1, wherein a=b, c=d, a+c is 0.5, b is at least 0.1, d is at least 0.2, and a+b+c+d=1.0, wherein the copoly(phthalazinone ether sulfone) composition has a weight average molecular weight of about 20,000 to about 170,000, a polydispersivity less than 6, and a glass transition temperature (Tq) less than or equal to 292° C., resulting in the copoly(phthalazinone ether sulfone) composition being melt processable.
