前言现代技术要求在高温下连续使用而性能稳定的各种高分子材料。在过去20年间,人们曾经合成了多种类型的耐高温的高聚物。聚苄就是一种最简单的芳香环次甲基结构的聚合物。它保留了聚苯的耐热性,又克服了它的性脆和难以加工的缺点,因此有广阔的前景。过去,国外曾通过氯苄路线合成聚苄,但是由于反应太剧烈,难以控制,聚合物中含氯量较高,所以没有广为生产。日本西崎俊一郎等曾希望从苄甲醚路线制备聚苄,但是由于没有
Preface Modern technology requires the continuous use of high temperature and stable performance of a variety of polymer materials. In the past 20 years, people have synthesized many types of high temperature polymers. Polybenzyl is one of the most simple aromatic ring methine structure of the polymer. It retains the heat resistance of polystyrene, but also overcome its brittle and difficult to process the shortcomings, so there is a bright future. In the past, polybenzyl was synthesized in foreign countries through the route of benzyl chlorobenzene. However, due to the reaction being too severe and difficult to control, the chlorine content in the polymer was high, so it was not widely produced. Junichiro Nishizaki Japan had hoped benzylbenzyl ether route from the preparation, but because there is no
