合成了N-五氟苯基马来酰亚胺（PFPMI）。合成了PFPMI与甲基丙烯酸甲酯（MMA）的均聚物和共聚物。单体竞聚率r（1）（PFPMI）为0.389，r（2）（MMA）为1.06。PFPMI的Q和e值计算为1.00和1.30。聚（PFPMI）和PMMA的折射率被发现是相似的：1.4989和1.4953在532 nm处，分别。共聚物没有表现出光散射，并且膜非常透明。PFPMI-共-MMA的玻璃化转变温度在140 ° C-180 ° C的范围内，其中PFPMI含量为18.8至65摩尔%，并且所获得的共聚物具有高的热稳定性（类似于370 ° C）。与纯PMMA相比，PFPMI-co-MMA的吸水率大大降低。(C)2011年由Elsevier Ltd.出版
N-pentafluorophenyl maleimide (PFPMI) was synthesized. The homo and copolymers of PFPMI with methyl methacrylate (MMA) were prepared. The monomer reactivity ratio, r(1) (PFPMI) and r(2) (MMA) were 0.389 and 1.06 respectively. Q and e values for PFPMI were calculated as 1.00 and 1.30. The refractive indexes of poly(PFPMI) and PMMA were found to be similar: 1.4989 and 1.4953 at 532 nm, respectively. The copolymers exhibited no light scattering, and the film was very transparent. The glass transition temperatures of the PFPMI-co-MMA were in the range of 140 degrees C-180 degrees C with the PFPMI content from 18.8 to 65 mol% and the copolymers obtained have high thermal stability (similar to 370 degrees C). The water absorption of PFPMI-co-MMA was greatly reduced as compared with that of pure PMMA. (C) 2011 Published by Elsevier Ltd.
