Abstract
Official abstract text for this publication.
Disclosed herein is a composition comprising a compatible blend of i) 60 to 85 weight percent of a linear poly(arylene sulfide), ii) 15 to 40 weight percent of a polyetherimide sulfone; and iii) 1 to 3 weight percent of a novolac resin having an average of 2 or more epoxy groups per molecule. Weight percent is based on the total weight of the composition. An article made from the composition has a tensile strength greater than or equal to 70 megaPascals (MPa), as determined by ASTM D638, an impact strength of greater than or equal to 3 kiloJoules per square meter (kJ/m 2 ), as determined by ASTM D256, and an elongation at break greater than or equal to 3 % as determined by ASTM D638. Methods of making the composition are also disclosed.
