trifunctional monomers based on renewable resources were prepared and subsequently polymerized via the Diels‐Alder (DA) polycondensation between furan and maleimide complementary moieties. Three basic approaches were considered for these nonlinear DA polycondensations, namely the use of (i) a bisfuran monomer in combination with a trismaleimide (A2 + B3 system) and (ii) a trisfuran monomer in conjunction
制备了基于可再生资源的新型三官能单体,随后通过呋喃和马来酰亚胺互补部分之间的Diels-Alder(DA)缩聚反应进行聚合。对于这些非线性DA缩聚,考虑了三种基本方法,即(i)将双呋喃单体与三马来酰亚胺(A 2 + B 3体系)组合使用和(ii)将三呋喃单体与双马来酰亚胺(A 3 + B 2体系)产生支链或交联材料,以及(iii)使用同时带有呋喃和马来酰亚胺端基的单体(A 2 B或AB 2系统),从而导致超支化结构。将retro-DA反应应用于随后的聚合物证实了其热可逆性。©2013 Wiley Periodicals,Inc. J Polym Sci A部分:Polym Chem,2013年
