采用合成时环境友好,在四氢呋喃中溶解性良好的二甲基苯酚钾作助引发剂,正丁基锂为引发剂、二甲苯为溶剂兼作链转移剂、2G为极性调节剂对二烯烃阴离子调聚进行了研究。考察了不同D_ROK/ n_BuLi对聚合物的特性粘度、分子量、分子量分布及微观结构的影响关系。制得的液体聚丁二烯和聚异戊二烯可用作绿色涂料的原料。
Synthesis of environmentally friendly, good solubility in tetrahydrofuran, potassium dimethyl phenol as a co-initiator, n-butyl lithium as an initiator, xylene as a solvent doubles as a chain transfer agent, 2G as a polar regulator of diolefin anion Tune was studied. The effect of different D_ROK / n_BuLi on intrinsic viscosity, molecular weight, molecular weight distribution and microstructure of the polymer was investigated. The resulting liquid polybutadiene and polyisoprene can be used as raw materials for green paints.
