BLENDS OF POLYSILOXANE/POLYIMIDE BLOCK COPOLYMER AND POLY(ARYLENE SULFIDE)
摘要:
Disclosed herein is a composition comprising a compatible blend of i) 24 to less than 84.5 weight percent of a linear poly(arylene sulfide), ii) 14 to 75 weight percent of a polysiloxane/polyimide block copolymer; and iii) 0.1 to less than 2.5 weight percent of a polymeric compatibilizer having 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 tensile elongation greater than or equal to 60% as determined by ASTM D638 and a Notched Izod impact strength greater than 50 joules per meter as determined by ASTM D256 at room temperature.
