Abstract

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/m²), 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.

Claims

1. A composition comprising a compatible blend of i) 65 to 75 weight percent of a linear poly (phenylene sulfide), ii) 20 to 35 weight percent of a polyetherimide sulfone comprising structural units having the formula

2. The composition of claim 1, wherein the novolac resin has an average of 6 or more epoxy groups per molecule.

3. The composition of claim 1, wherein the novolac resin has an average of 20 or more epoxy groups per molecule.

4. The composition of claim 1, further comprising a reinforcing filler.

5. The composition of claim 4 wherein the reinforcing filler comprises glass beads, glass flake, milled glass, glass fibers, or combinations thereof.

10. The composition of claim 1, wherein the polyetherimide sulfone is derived from dianhydrides comprising a combination of bisphenol-A dianhydride and oxydiphthalio anhydride, and a diamino diphenyl sulfone.
