将催化剂FeCl2/亚氨基二乙酸用于原子转移自由基聚合制备PS -b -PMMA嵌段共聚物。大分子引发剂和嵌段共聚物的相对分子质量及其分布用GPC测定 ,共聚物的结构用红外光谱表征 ,玻璃化转变温度用DSC测定。
The catalyst FeCl2 / iminodiacetic acid was used in atom transfer radical polymerization to prepare PS-b-PMMA block copolymer. The relative molecular mass and distribution of macromolecular initiator and block copolymer were determined by GPC. The structure of copolymer was characterized by FTIR and the glass transition temperature was determined by DSC.
