摘要
以苯乙烯为单体,六次甲基四胺为配体,四氯化碳为引发剂,铁粉为催化剂,水合肼为还原剂,水为溶剂,在较适宜的温度下,采用单电子转移活性自由基聚合的方法,制备了相对分子质量及其分布可控的聚苯乙烯。实验结果表明,最佳反应条件为:溶剂为5 mL,催化剂铁丝质量为0.6 g,引发剂四氯化碳用量为0.3 mL,还原剂水合肼用量为0.4 mL,同时温度越高转化率越高。
A kind of polystyrene of controllable relative molecular mass and relative molecular mass distribution was prepared at a suitable temperature by single electron transfer living radical polymerization method with styrene as the monomer, hexamethylene tetramine as the ligand, carbon tetrachloride as the initiator, iron powder as the catalyst, hydrazine hydrate as the reducer and water as the solvent. According to the experimental results, the optimum reaction conditions are as follows： use of solvent： 5 mL, mass of iron wire, the catalyst ： 0.6 g, use of carbon tetrachloride, the initiator： 0. 3 mL, use of hydrazine hydrate, the reducer： 0.4 mL. It was found that the higher the temperature is, the higher the conversion is.
