六十年代以来,国外对耐高温高分子,特别是耐高温杂环高分子,进行了大量工作,取得了很多成果,国内也进行了广泛的研究工作。但在这些工作中,既具有优良的耐高温性能,又具有良好的成型工艺性能,并能付诸实际应用的品种却不很多。我们根据自己的工作实践以及国外的一些发展趋势,认为先合成一种具有耐高温结构并含有能进行加成聚合的基团的单体或低聚物,然后在成型过程中聚合成交联结构,如此所得的高分子既具有耐高温性能,又可克服难以成型的缺点,适合作为增强塑料、模压塑料、涂料等方面的应用。对具体的结构设计,我们是这样考虑的:对耐温结
Since the 1960s, a great deal of work has been done abroad on high temperature resistant polymers, especially high temperature resistant heterocyclic polymers, and many achievements have been made. A great deal of research work has also been carried out domestically. However, in these work, not only has excellent high temperature performance, but also has good molding process performance, and can be put into practical application of the species is not many. Based on our own work practices and some foreign development trends, we believe that a monomer or oligomer having a high temperature-resistant structure and containing an addition-polymerizable group may be synthesized and then polymerized into a crosslinked structure during the molding process. The resulting polymer not only has high temperature performance, but also overcome the shortcomings difficult to shape, suitable as a reinforced plastic, molded plastic, paint and other aspects of the application. For specific structural design, we consider this: the temperature resistance knot
