本研究探讨了具有空间要求高的反应中心的聚合物的后聚合改性的挑战性方法。因此，研究了官能化聚亚甲基部分的一般可能性。以[（L-脯氨酸）Rh-I（1，5-二甲基-1，5-环辛烯）]为催化剂，通过重氮乙酸苄酯的聚合，合成了聚2-亚甲基乙酸苄酯。随后，修改C1聚合的聚（苄基2-亚甲基-乙酸酯）与胺进行了分析，并得到的数据集进行了比较，与实验数据来自C2模拟聚（丙烯酸苄酯）。这是第一次研究后聚合改性利用密集官能化聚亚甲基为起始材料。(c)2015 Wiley Periodicals，Inc. J.波利姆科学，A部分：聚合物2016，54，686-691
The present study investigates the challenging approach of post-polymerization modification on polymers with a sterically demanding reaction center. Therefore, the general possibility to functionalize polymethylene moieties was investigated. Poly(benzyl 2-ylidene-acetate) was synthesized by polymerization of benzyl 2-diazoacetate utilizing [(L-prolinate)Rh-I(1,5-dimethyl-1,5-cyclooctadiene)] as a catalyst. Subsequently, the modification of C1 polymerized poly(benzyl 2-ylidene-acetate) with amines was analyzed and the obtained data set was compared with experimental data derived for the C2 analog poly(benzyl acrylate). This is the first study on post-polymerization modification utilizing densely functionalized polymethylenes as starting materials. (c) 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.
