研究了以PhCH2Cl/MoCl3(OC8H17)2/PPh3体系引发异戊二烯的原子转移自由基聚合,所得聚合物的相对分子质量与转化率呈线性增加,相对分子质量分布为1.9 ~2.2。紫外光谱分析表明,该聚合反应符合原子转移自由基聚合机理。
The atom transfer radical polymerization of isoprene induced by PhCH2Cl / MoCl3 (OC8H17) 2 / PPh3 system was studied. The relative molecular mass and the conversion of the obtained polymer linearly increased with the molecular weight distribution of 1.9-2.2. UV spectroscopy showed that the polymerization met the atom transfer radical polymerization mechanism.
