近年来,有关高性能树脂聚酰亚胺共混物的研究日益引起人们的关注。已经发现许多种分子结构不同的聚酰亚胺之间,聚酰亚胺与聚苯并咪唑,或聚醚醚酮能形成完全相容的共混体系,从而扩大了高性能树脂聚酰亚胺的应用范围。 酚酞型聚醚醚酮(PEK-C)是由我所研究开发出的一种新型的聚醚醚酮类高性能树脂,它具有良好的可溶性,优异的机械强度和加工流动性,已广泛应用于结构材料及复合材料的制备。为进一步扩大该树脂的应用范围,本实验室在PEK-C共混物的研究做了大量的工作。本工作研究了聚醚酰亚胺(PEI)/PEK-C共混体系的相容性。PEI和PEK-C的分子结构如下:
In recent years, more and more attention has been paid to the research of high performance polyimide resin blends. It has been found that many kinds of polyimides with different molecular structures, polyimide and polybenzimidazole, or polyetheretherketone can form a completely compatible blend system, thereby expanding the high performance resin polyimide The scope of application. Phenolphthalein polyetheretherketone (PEK-C) is a new type of polyetheretherketone high performance resin researched and developed by us. It has good solubility, excellent mechanical strength and processing fluidity. It has been widely used Preparation of structural materials and composite materials. To further expand the scope of the application of the resin, the laboratory in the PEK-C blend of a lot of work done. This work studied the compatibility of polyetherimide (PEI) / PEK-C blends. The molecular structure of PEI and PEK-C is as follows:
