A new method for linear polymerization of maleimides via the Diels–Alder reaction has been developed. This method involves use of a new cross-linking agent, benzene-3,4-dimethylenesuccinimide, which can be generated in situ from its thiophene precursor, benzene-2,5-dihydrothiophene-3,4-dicarboximide-S,S-dioxide. This new cross-linking agent is reasonably reactive, readily prepared, and stable at room
已开发出一种通过 Diels-Alder 反应线性聚合马来酰亚胺的新方法。该方法涉及使用新的交联剂苯-3,4-二亚甲基琥珀酰亚胺,它可以从其噻吩前体苯-2,5-二氢噻吩-3,4-二甲酰亚胺-S,S-二氧化物原位生成. 这种新型交联剂具有相当的反应性、易于制备且在室温下稳定。已经合成了一种受控分子量的低聚物并将其应用于聚合以产生高度热稳定的聚酰亚胺。© 2006 Wiley Periodicals, Inc. 杂原子化学 17:648–652, 2006; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.20249
