Abstract
A thermoplastic molding composition which comprises a mixture of two thermoplastic synthetic polymers, which are at least partially miscible with one another, is disclosed. In one embodiment, the molding composition comprises a mixture of styrene-citraconic anhydride copolymer and methyl-methacrylate-styrene copolymer.
Claims6
A thermoplastic molding composition comprising a mixture of two at least partially miscible thermoplastic synthetic polymers, one polymer being styrene-citraconic anhydride copolymer and the other polymer being selected from the group consisting of polymethylmethacrylate and methylmethacrylate-styrene copolymer in which said styrene-citraconic anhydride copolymer contains less than about 50 weight percent citraconic anhydride.
A thermoplastic molding composition comprising a totally miscible mixture of styrene-citraconic anhydride copolymer and polymethylmethacrylate homopolymer.
