一种半芳香族聚酰胺树脂及其制备方法和由其组成的聚酰胺模塑组合物
摘要：
本发明公开了一种半芳香族聚酰胺树脂，包括：a）基于全部二酸含量，70mol%-100mol%的对苯二甲酸和0-30mol%的其它二酸；b）基于全部二胺含量，10mol%-100mol%的含有11-24个碳原子的直链脂肪族二胺和0-90mol%的1,6-己二胺；c）基于全部二胺和二酸的量，0-30mol%的氨基酸或内酰胺；d）基于对苯二甲酸单元含量，0-10mol%含有2-24个碳原子的单羧酸；并且，所述半芳香族聚酰胺树脂至少含有三种衍生自a）、b）或c）的重复单元。本发明人出人意料的发现，通过采用基于特定组成的11-24个碳原子的直链脂肪族二胺和二酸，得到的半芳香族聚酰胺树脂具有优良的颜色；同时也使得由该半芳香族聚酰胺树脂组成的聚酰胺模塑组合物具有优良的颜色。
摘要（英）：

The invention discloses semi-aromatic polyamide resin. The semi-aromatic polyamide resin is prepared from the following components: (a) 70 to 100 mol percent of terephthalic acid and 0 to 30 mol percent of other diacids based on the content of whole diacid; (b) 10 to 100 mol percent of straight chain aliphatic diamine containing 11 to 24 carbon atoms and 0 to 90 mol percent of 1,6-hexanediamine based on the content of the whole diamine; (c) 0 to 30 mol percent of amino acid or lactam based on the content of the whole diacid and diamine; (d) 0 to 10 mol percent of monocarboxylic acid containing2 to 24 carbon atoms based on unit content of the terephthalic acid; in addition, the semi-aromatic polyamide resin contains at least three repeative units derived from (a), (b) or (c). The inventorsurprisingly finds that the semi-aromatic polyamide resin obtained by the straight chain aliphatic diamine based on a specific composition of 11 to 24 carbon atoms and diacid, has excellent color; meanwhile, a polyamide molding compound prepared from the semi-aromatic polyamide resin is enabled to have excellent color.
