Abstract
Compositions made from a polyarylate or polyester carbonate containing greater than about 50 mole % resorcinol based ester linkages give miscible blends with polyimide resins. The blends of polyimides and resorcinol based polyesters or resorcinol based polyester carbonates also give miscible blends when combined with other aryl alky polyester resins.
Claims21
A composition comprising a miscible polymer blend of one or more polyimide resins and a second resin selected from the group consisting of resorcinol based polyester carbonates, resorcinol based polyarylates and mixtures thereof, wherein the second resin has at least 50 mole % aryl ester linkages derived from resorcinol, based on the total mole % of linkages in the second resin.
A composition comprising a miscible polymer blend of:
- a) 1-99% of a polyetherimide,
- b) 99-1% of an aryl polyester resin containing at least 50 mole % resorcinol linkages based on the total mole % of linkages in the aryl polyester resin,
- c) 0-30% of an aryl alkyl polyester
- d) 0-2% of a phosphorus containing stabilizer.
