以aa′-二溴对二甲苯（DBX）/ CuBr/2，2 ′-联吡啶（bipy）为引发体系，通过原子转移自由基聚合（ATRP）制备了分子量和分子量分布较窄的溴化双端聚苯乙烯（Br-PSt-Br）和聚甲基丙烯酸甲酯（Br-PMMA-Br）。在微波辐射（MI）条件下，以CuBr/bipy为催化剂体系，将前体溴封端聚合物与富勒烯C60进行功能化反应。采用凝胶渗透色谱（GPC）、紫外可见光谱（UV-vis）、红外光谱（FT-IR）、热重分析（TGA）、差示扫描量热分析（DSC）、核磁共振氢谱（1H NMR）和碳谱（13 C NMR）等手段对产物进行了表征。结果表明，微波辐射能显著提高富勒烯化反应速率，且微波辐射对C60封端聚合物的物理性能和结构没有影响。© 2005 Wiley Periodicals，Inc.应用聚合物科学杂志99：828-834，2006
Bromo-Double-Terminated polystyrene (Br-PSt-Br) and poly(methyl methacrylate) (Br-PMMA-Br) with predesigned molecular weight and narrow polydispersity were prepared by atom transfer radical polymerization (ATRP) using the initiating system aa′-dibromo-p-xylene(DBX) / CuBr/2,2′-bipyridine(bipy). The precursor bromo-terminated polymers were subsequently functionalized with fullerene C60 using CuBr/bipy as the catalyst system under microwave irradiation (MI). The telechelic C60 end-capped products were characterized by gel permeation chromatography (GPC), UV-vis, FT-IR, TGA, DSC, 1H NMR, and 13C NMR. The results showed that microwave irradiation could significantly increase the rate of fullerenation reaction, and the physical properties and structure of the C60 end-capped polymers are not modified by the use of the microwave. © 2005 Wiley Periodicals, Inc.
