Claims
- 1. A thermally processable, polyurethane composition comprising from about 35 to about 90 weight percent of a thermally processable, rigid polyurethane and from about 65 to 10 weight percent of a mass ABS either dispersed in or co-continuous with the polyurethane, said mass ABS resin being comprised of from about 5 to about 35 weight percent rubber and from about 95 to about 65 weight percent of a copolymer of acrylonitrile and styrene.
- 2. The composition of claim 1 wherein the polyurethane consists essentially of the reaction product of diphenylmethane-4,4'-diisocyanate or a liquid polymer of diphenylmethane-4,4'-diisocyanate and cyclohexanedimethanol, cyclohexanediol or a mixture thereof.
- 3. The composition of claim 1 comprising from about 45 to about 75 weight percent of the polyurethane and from about 25 to about 55 weight percent of the mass ABS resin.
- 4. The composition of claim 3 wherein the polyurethane has a glass transition temperature greater than 115.degree. C.
- 5. The composition of claim 4 wherein the mass ABS resin contains from about 10 to about 25 weight percent of rubber and from about 90 to about 75 weight percent of a copolymer of from about 22 to about 40 weight percent of acrylonitrile and from about 60 to about 78 weight percent of styrene.
- 6. A thermally processable, polyurethane composition comprising from about 65 to about 35 weight percent of a thermally processable, rigid polyurethane consisting essentially of the reaction product of an organic diisocyanate and a cyclic diahl wherein at least 50 weight percent of the cyclic diahl is cyclohexane dimethanol and from about 35 to about 65 weight percent of a mass polymerized ABS resin being either dispersed in or co-continuous with the polyurethane.
- 7. The composition of claim 6 comprising from about 35 to about 85 weight percent of the thermoplastic polyurethane and from about 65 to 15 weight percent of the mass ABS resin.
- 8. The composition of claim 7 wherein the polyurethane has a glass transition temperature greater than 95.degree. C.
