摘要：

用酶促聚合和原子转移自由基聚合相结合的"一锅法"合成了聚甲基丙烯酸正丁酯嵌段聚10-羟基癸酸[PBMA-b-P(10-HD)], 通过核磁共振(1H NMR)、傅里叶红外光谱(FTIR)和凝胶渗透色谱(GPC)对其结构以及分子量与其分子量分布进行了表征, 并通过动态光散射仪(DLS)和原子力显微镜(AFM)对聚合物在水溶液中的性质进行了研究. 所得嵌段聚合物纳米粒子呈球形结构, 平均直径为135 nm左右.

Abstract:

Diblock copolymer poly(n-butyl methacrylate)-block-poly(10-hydroxydecanoate)(PnBA-b-PHD) was prepared by one pot strategy via combination of enzymatic polymerization of 10-hydroxydecanoate(HD) and atom transfer radical polymerization(ATRP) of n-butyl methacrylate(nBA). The obtained copolymer was characterized by 1H NMR, FTIR and gel permeation chromatography(GPC). The solution properties of diblock copolymer into water in dry state were examined by atom force microscopy(AFM), in which well-dispersed spherical micellar structure in mono-modal pattern was clearly observed with a size value around 135 nm. Whereas the hydrodynamic diameter of the aggregates surrounded in tetrahydrofuran(THF) was determined by dynamic light scattering(DLS) instrument.

Key words: One-pot, Enzymatic self condensation polymerization(eSCP), Atom transfer radieal polymerization(ATRP), Diblock copolymer
