Polymide/polyarylate resin composition and molded product thereof

A resin composition comprising:

• (A) a polyimide comprising a recurring unit represented by the following formula (1):
• wherein Ar0 is an aromatic hydrocarbon group having 6 to 15 carbon atoms represented by the following formula:
• wherein X is a single bond, sulfonyl group, alkylene group having 1 to 3 carbon atoms or haloalkylene group having 1 to 3 carbon atoms, and R1 is at least one group selected from the group consisting of a divalent residual group obtained by removing two amino groups from an aliphatic diamine having 2 to 30 carbon atoms and a divalent residual group obtained by removing two amino groups from an alicyclic diamine having 4 to 30 carbon atoms, and
• (B) at least one polymer selected from the group consisting of a polyarylate comprising at least one recurring unit selected from the group consisting of a recurring unit represented by the following formula (2-1):
• wherein Ar1 is an aromatic hydrocarbon group having 6 to 18 carbon atoms and Ar2 is an aromatic hydrocarbon group having 6 to 30 carbon atoms or a combination of the aromatic hydrocarbon group and an aliphatic hydrocarbon group having 2 to 10 carbon atoms, and a recurring unit represented by the following formula (2-2):
• wherein Ar3 is an aromatic hydrocarbon group having 6 to 18 carbon atoms, and a polyester carbonate comprising at least one of the above recurring units and a recurring unit represented by the following formula (2-3):
• wherein Ar4 is an aromatic hydrocarbon group having 6 to 30 carbon atoms, the amount of the polyimide (A) being 0.05 to 99.95 wt % and the amount of the polymer (B) being 99.95 to 0.05 wt % based on the total weight of the polyimide (A) and the polymer (B).
