A copolyamide comprising undecamethylenehexahydroterephthalamide unit and hexamethylenehexahydroterephthalamide unit and having 57 to 83 percent of trans isomer ratio of hexahydroterephthalic acid residues, is suitable for injection and extrusion moldings. The copolyamide is prepared by a process comprising heating of equimolar salt of undecamethylenediamine and hexahydroterephtha- lie acid and equimolar salt of hexamethylenediamine and hexahydroterephthalic acid at maximum temperature of about 280 to 360 °C, whereby the copolyamide is stably metl-polymerized. The copolyamide molding composition comprising the copolyamide and inorganic reinforcing agent, can be formed into various molded articles having excellent properties.
一种由十一亚甲基六氢对苯二甲酰胺单元和六亚甲基六氢对苯二甲酰胺单元组成的共聚酰胺,其六氢对苯二甲酸残留物的反式异构体比率为 57%至 83%,适用于注射和挤压成型。 该共聚酰胺的制备过程包括在最高温度约 280 至 360 °C 下加热十一亚甲基二胺和六氢对苯二甲酸的等摩尔盐以及六亚甲基二胺和六氢对苯二甲酸的等摩尔盐,从而使共聚酰胺稳定地发生偏聚。 由该共聚酰胺和无机增强剂组成的共聚酰胺成型组合物可制成各种具有优异性能的成型制品。
