用NMR分析配合计算机分峰,分析和计算共缩聚物序列结构参数的方法,研究了单体、酸吸收剂的加料顺序和两种二元胺的投料比对由已二胺和乙二胺为代表的脂肪族二胺,对苯二胺和对苯二甲酰氯合成的芳香-脂肪族共聚酰胺序列结构的影响。结果表明,在脂肪族二胺用量占二胺总量33.3%(mol)时,所获得的共聚物具有最大的无规度和最短的数均序列长度。
NMR analysis of the computer with the points, analysis and calculation of the structure parameters of the copolycondensation method, the monomer, acid absorbent and the feeding sequence of two diamine feed ratio of diamine and ethylenediamine as Aliphatic aliphatic diamines represented by p-phenylenediamine and terephthaloyl chloride synthesized aromatic-aliphatic copolyamide sequence structure. The results showed that when the amount of aliphatic diamine accounted for 33.3% (mol) of total diamine, the copolymer obtained had the largest randomness and the shortest number average sequence length.
