甲基丙烯酸糠酯（FMA）聚合物是令人感兴趣的材料，因为糠基作为侧基中的反应性二烯官能团的存在。 FMA和MMA的共聚物是通过CuCl催化的原子转移自由基聚合（ATRP）与HMTETA作为配体在90℃下制备的。由于涉及反应性二烯基团的几个副反应，传统的自由基聚合很难制备。使用 H-1 NMR 研究计算共聚物组成。 FMA 和 MMA 的反应率（r(1) 和 r(2)）使用 Finemann-Ross 和 Kelen-Tudos 线性化方法确定。获得的反应活性比为r(1) = 1.56 和r(2) = 0.56。使用共聚物的反应性二烯和作为亲二烯体的马来酰亚胺进行狄尔斯-阿尔德化学。有趣的是，FT-IR 光谱和 DSC 研究证明所得材料具有热可逆性。
Polymers of furfuryl methacrylate (FMA) are interesting materials because of the presence of the furfuryl group as the reactive diene functionality in the pendent group. Copolymers of FMA and MMA were prepared using atom-transfer radical polymerization (ATRP) catalyzed by CuCl, in combination with HMTETA as a ligand at 90 degrees C. It was very difficult to prepare by conventional radical polymerization because of several side reactions involving the reactive diene group. The copolymer composition was calculated using H-1 NMR studies. The reactivity ratios of FMA and MMA (r(1) and r(2)) were determined using the Finemann-Ross and Kelen-Tudos linearization methods. The reactivity ratios obtained were r(1) = 1.56 and r(2) = 0.56. Diels-Alder chemistry was carried out using the reactive diene of the copolymers and a maleimide as the dienophile. Interestingly, the resultant material was observed to be thermoreversible as evidenced by FT-IR spectroscopy and DSC studies.
