Title:

POLYETHERSULFONE COMPOSITION, METHOD OF MAKING AND ARTICLES THEREFROM

Document Type and Number:

WIPO Patent Application WO2005052029

Kind Code:

A3

Abstract:

A polyethersulfone composition is disclosed which comprises structural units derived from a monomer mixture comprising bisphenol-A and at least 55 mole percent of 4,4'-biphenol based on total moles of diphenolic monomers, wherein the polyethersulfone has a minimum weight average molecular weight which is a function of the mole percent of structural units derived from biphenol monomer. In addition the polyethersulfones possess a notched Izod impact strength value of greater than 470 Joules per meter as measured by ASTM D256.
