POLY(ARYL ETHER SULFONE) COMPOSITIONS HAVING IMPROVED FLOW PROPERTIES

摘要

immiscible blends of poly (arylu00e9ther sulfone) have improved fluidity.these compositions contain (a) from 80 to 99% by weight of a poly (approximately arylu00e9ther sulfone) having a glass transition temperature (tg) of second order over 240u00b0c, and (b) from 1 to 20% by weight of a second poly (sulfone with a arylu00e9ther) tg less than 225 c approximately.these compositions retain the characteristics of their constituents and are very attractive mechanical properties and heat resistance are excellent.
