采用原子转移自由基聚合（ATRP）方法合成了一种带有侧链糠基的聚甲基丙烯酸酯。否则难以通过常规自由基聚合制备，因为涉及糠基的反应性二烯官能团的几个副反应。使用这种反应性糠基进行了成功的Diels-Alder（DA）化学。一组定制的聚合物作为二烯和双马来酰亚胺作为亲二烯体。有趣的是，观察到所得材料是热可逆的，如通过FT-IR和DSC研究所证明的。在DA化学中应用具有受控分子结构和反应性二烯官能度的定制聚合物的这个实例将为制备更新的定制可逆材料开辟新的可能性。(c)2007 Wiley Periodicals，Inc.
A tailor-made polymethacrylate bearing a pendant furfuryl group was prepared by atom transfer radical polymerization (ATRP), an important method of recent advances in controlled radical polymerization. It was otherwise difficult to prepare via conventional radical polymerization, because of several side reactions involving the reactive diene functionality of the furfuryl group. Successful Diels-Alder (DA) chemistry was carried out using this reactive furfuryl. group of the tailor-made polymer as diene and a bismaleimide as a dienophile. Interestingly, the resultant material was observed to be thermoreversible as evidenced by FT-IR and DSC studies. This example of application of a tailor-made polymer having controlled molecular architecture and with reactive diene functionality in DA chemistry will open new possibilities to prepare newer tailor-made reversible materials.
