分子式:
CAS号:

性质:由酰亚胺环和酯键有规则交替排列的一类聚合物。可由含酯键的二元胺、二异氰酸酯或二酐采用通常的聚酰亚胺合成路线制备,也可由含酰亚胺环的芳族二羧酸与饱和二元醇缩聚而成。主要用作F,H级电机浸渍绝缘漆、耐热绝缘薄膜和漆包线漆。薄膜呈黄色透明状、坚韧、表面硬度3H,强度高于普通聚酰亚胺薄膜。软化温度为300℃,长期使用温度为230~240℃,拉伸强度为103MPa(23℃)和43MPa(200℃),拉伸模量为3.04GPa(23℃),断裂伸长率为14%(23℃)。液晶聚酯酰亚胺是在聚酰亚胺主链中引入芳酯热致介晶单元,可改善成型加工性,提高材料的强度和模量、降低热膨胀系数和吸湿性,具有很好的发展前景。
