Copolyamide from 1,4-cyclohexane dicarboxylic acid and diamine mixture |
摘要 |
A copolyamide comprised of undecamethylenehexahydroterephthalamide units and hexamethylenehexahydroterephthalamide units having a trans isomer ratio of hexahydroterephthalic acid residues of 57 to 83 percent is provided. The copolyamide is suitable for injection and extrusion molding. The copolyamide is prepared by a process comprising heating an equimolar salt of undecamethylenediamine and hexahydroterephthalic acid and an equimolar salt of hexamethylenediamine and hexahydroterephthalic acid at a maximum temperature of about 280 to 360 DEG C. to stably melt-polymerize the copolyamide. A copolyamide molding composition comprised of the copolyamide and an inorganic reinforcing agent can be formed into various molded articles having excellent properties.
