in a controlled polymerization with linear kinetics, molecular weights which increase with conversion and narrow polydispersity indexes. Mono and difunctional PHEMAGl macroinitiators were used to synthesize the amphiphilic di and triblock glycopolymers with n‐butyl acrylate, verifying their living character. The self‐assembly of these glycopolymers in distilled water and in 0.1M NaCl solutions was studied
首次报道了未保护的糖单体2-[(D-氨基葡萄糖-2 N-基)羰基]氧基}甲基丙烯酸乙酯(HEMAG1)的原子转移自由基聚合。在DMF溶液中,以2-溴异丁酸乙酯和1,2-双(溴异丁酰氧基)乙烷为单或双官能引发剂,使用CuBr / N,N,N',N',N',N'-五甲基二乙烯三胺催化体系进行受控聚合。(80 %w / w)分别在40和50°C下。HEMAG1的聚合导致具有线性动力学,分子量随转化率增加和窄的多分散指数而受控的聚合。使用单官能和双官能的PHEMAG1大分子引发剂合成具有n的两亲性di和triblock糖聚合物丙烯酸丁酯,证实其活性。通过动态光散射研究了这些糖聚合物在蒸馏水和0.1M NaCl溶液中的自组装,显示了氢键和疏水部分的作用。另外,检查了它们与伴刀豆球蛋白A凝集素的相互作用,证明了分子量和共聚物组成的影响。©2010 Wiley Periodicals,Inc.
