摘要
芳香聚酰胺具有优异的热稳定性,但在溶剂中的溶解性能较差。人们发现在聚酰胺中的苯环上引进甲基取代基是改善聚合物溶解性能的一种有效的途径,Takatsuka等曾合成了一系列一取代和二取代甲基的芳香聚酰胺,聚合物的溶解性有较大的改善。但尚未见关于三甲基取代聚合物的合成报道。
The aromatic polyamides were prepared by polyeondensation of terephthaloyl or isophthaloyl dichloride with 2,4,6-trimethyl-1,3-phenylenediamine. The influences of the monomer concentration and polymerization conditions on the degree of polymerization were studied. The polymers obtained have a greater solubility than common polyamides with less methyl groups on the benzene ring.
