以N-氯代丁二酰亚胺（NCS）为引发剂，分别以CuCl/PMDETA（N，N，N′，N ′，N′′-五甲基二乙烯三胺）、CuCl/MA5-DETA（N，N，N ′，N ′，N′-五（甲基丙烯酸酯）二乙烯三胺）和CuCl/bipy（bipy 2，2′-联吡啶）为催化体系，实现了甲基丙烯酸甲酯（MMA）的原子转移自由基聚合（ATRP）.结果表明，该聚合反应具有典型的可控/活性自由基聚合特征。用1HNMR对聚合物的端基进行了分析，证明NCS是ATRP的引发剂。与NBS相比，NCS引发的聚合速率较慢，所得聚合物的分子量分布较窄。
Atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA) was achieved, using N-chloro-succinimide (NCS) as an initiator together with catalytic system CuCl/PMDETA (N,N,N′,N′,N′′-pentamethyldiethyl-enetriamine), CuCl/MA5-DETA (N,N,N′,N′,N′′-penta(methylacrylate)diethylenetriamine), and CuCl/bipy (bipy2,2′-bipyridyl) respectively. The results indicated that the polymerization possessed typical controlled/living radical polymerization characteristics. The analysis for terminal group of obtained polymer by 1H NMR proved that NCS is an initiator for ATRP. In comparison with NBS, the polymerization rate was slower and the resulted polymer had narrower molecular weight distribution (MWD) when NCS was employed as the initiator.
