摘要
研究了以双酚A醚酐与二甲基联苯二胺为体系的缩聚反应,由其制备的聚醚酰亚胺(PEI)薄膜具有优异的透光率,低介电常数和较低的热膨胀系数。这种新型耐热型透明的新材料在光学领域有广泛的应用。
The process of the condensation and polymerization of bisphenol a dianhydride and dimethyl bisphenyl diamine was studied. Polyehthcrimide （PEI） film was made of it has excellent transparent rate, low dielectric constant and low thermal expansion coefficients. The new heat-resistant and transparent material is used widely in optical field.
