Described herein are poly(aryl ether sulfone) blends possessing improved flow properties. The novel compositions contain (a) from about 80 to about 99 percent by weight of a poly(aryl ether sulfone) having a second order glass transition temperature (Tg) higher than about 230 DEG C., and (b) from about 1 to about 20 percent by weight of a second poly(aryl ether sulfone) having a Tg below about 230 DEG C. The compositions described herein retain the very attractive characteristics of their constituents, and display excellent mechanical properties and heat resistance.
