合成了2-氨基-4-氯-5-甲酰基噻唑和2-氨基-4-氯-5-二氰乙烯基噻唑.分别将其与亚硝酰硫酸反应配制成重氮盐,通过在极性溶剂中与含苯胺残基的环氧树脂类前体聚合物BP-AN进行重氮偶合反应,得到了两种含噻唑偶氮苯生色团的环氧树脂类聚合物BP-1A-T-F和BP-1A-T-2CN.利用仪器分析手段对其结构、光谱特性和热性能进行了表征,BP-1A-T-F和BP-1A-T-2CN的最大吸收波长分别为579nm和650nm;玻璃化转变温度152℃和149℃.
2-Amino-4-chloro-5-formylthiazole and 2-amino-4-chloro-5-dicyanovinylthiazole were synthesized and reacted with nitrosylsulfuric acid to form diazonium salts. A kind of epoxy resin precursor polymer BP-AN containing aniline residues was subjected to diazo coupling reaction in the solvent to obtain two kinds of epoxy resin polymers BP-1A-TF containing thiazolylazo benzene chromophore BP-1A-T-2CN and BP-1A-T-2CN.The structures, spectral properties and thermal properties of BP-1A-T-2CN were characterized by means of instrumental analysis.The maximum absorption wavelengths of BP- The transition temperatures are 152 ° C and 149 ° C.
