Abstract
Abstract A thermoplastic molding composition which comprises a blend of: (A) a copolymer having recurring units of a monoalkenyl aromatic monomer and recurring units of an α,β-ethylenically unsaturated dicarboxylic anhydride N-substituted imide, and (B) a hydrogenated elastomeric block copolymer having at least one substantially completely hydrogenated diene polymer mid block and at least two monoalkenyl arene polymer end blocks in which at least a portion of the arene groups contained in the end blocks are substituted with at least one substituent selected from the group consisting of nitro, cyano and trifluoromethanesulfonyl.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
95 words
A moldable compound comprising: (1) a blend of: (A) a copolymer having recurring units of a monoalkenyl aromatic monomer and recurring units of an α,β-ethylenically unsaturated dicarboxylic anhydride N-substituted imide, and (B) a hydrogenated elastomeric block copolymer having at least one substantially completely hydrogenated diene polymer mid block and at least two monoalkenyl arene polymer end blocks in which at least a portion of the arene groups contained in the end blocks are substituted with at least one substituent selected from the group consisting of nitro, cyano, and the trifluoromethanesulfonyl, and (2) a thermoplastic resin.
Claim 2
Dependent Claim
95 words
A moldable compound comprising: (1) a blend of: (A) a copolymer having recurring units of a monoalkenyl aromatic monomer and recurring units of an α,β-ethylenically unsaturated dicarboxylic anhydride N-substituted imide, and (B) a hydrogenated elastomeric block copolymer having at least one substantially completely hydrogenated diene polymer mid block and at least two monoalkenyl arene polymer end blocks in which at least a portion of the arene groups contained in the end blocks are substituted with at least one substituent selected from the group consisting of nitro, cyano, and the trifluoromethanesulfonyl, and (2) a thermoplastic resin.
Claim 3
Dependent Claim
15 words
