Claims
- 1. An injection moldable composition comprising (1) a crystallizable polyamide component comprising recurring units ##STR3## wherein R comprises a divalent aliphatic radical and the mole ratios of the dicarboxylic acid moieties of the A, C and B units are 45-65:25-55:0-20, respectively, and (2) a fibrous or particulate filler material.
- 2. The composition of claim 1 wherein R comprises at least one divalent straight chain or cyclic aliphatic radical of about 4 to 20 carbon atoms having up to one methyl substituent per carbon atom.
- 3. The composition of claim 1 wherein the composition comprises about 10 to about 60 weight percent fibrous or particulate filler component based on weight of the filled composition, said filler selected from the group consisting of glass fibers, graphitic carbon fibers, amorphous carbon fibers, synthetic polymeric fibers, aluminum fibers, aluminum silicate fibers, aluminum oxide fibers, titanium fibers, magnesium fibers, rock wool fibers, steel fibers, tungsten fibers, cotton, wool and wood cellulose fibers.
- 4. The composition of claim 3 wherein R comprises hexamethylene or octamethylene.
- 5. The composition of claim 3 wherein R is hexamethylene.
- 6. The composition of claim 3 wherein the mole ratios of the dicarboxylic acid moieties of the A, C and B units are about 50:50:0.
- 7. A molded object comprising the composition of claim 1.
- 8. An injection moldable composition comprising (1) a crystallizable polyamide component comprising recurring units ##STR4## wherein R comprises a divalent aliphatic radical and the mole ratios of the dicarboxylic acid moieties of the A, C and B units are 45-65:25-55:0-20, respectively, and (2) a fibrous or particulate filler component comprising glass fibers.
- 9. An injection moldable composition comprising (1) a crystallizable polyamide component comprising recurring units ##STR5## wherein R comprises hexamethylene and the mole ratios of the dicarboxylic acid moieties of the A, C and B units are 45-65:25-55:0-20, respectively, and (2) about 10 to about 60 weight percent of a fibrous or particulate filler component comprising glass fibers, based on weight of the filled composition.
- 10. The composition of claim 9 wherein the mole ratios of the dicarboxylic acid moieties of the A, C and B units are about 50:50:0.
- 11. A molded object comprising the composition of claim 10.
- 12. A molded object comprising the composition of claim 9.
