| 摘 要： | 以TiCl4/Al(i-Bu)3为引发体系,用本体预聚合法引发1-十二烯聚合,制备高减阻性能的油溶性减阻剂。研究了二苯基二甲氧基硅烷(DDS)、预聚与后聚单体体积比、预聚温度和预聚时间对聚合物减阻性能的影响。结果表明,在优化的合成工艺条件下,能够合成减阻率为50.67%,增输率为48.1%的聚合物(添加量为10 mg/L)。通过IR、GPC和1H-NMR分析表明:转化率接近100%,重均相对分子质量Mw为3.58×106、相对分子质量分布宽度指数Mw/Mn为4.44。采用预聚工艺较本体直接聚合可以节省主催化剂用量达40%以上。

| Abstract: | Using TiCl_4/Al(i-Bu)_3 as initiating system to polymerize 1-dodecene by bulk prepolymerization,high efficiency oil-solvent drag reducer was synthesized.The influence of DDS,the 1-dodecene volume ratio of prepolymerization to postpolymerization,prepolymerization temperature and prepolymerization time on drag reducing efficiency were studied.Under the optimal synthesis conditions,the drag reducing performance of the polymer was better.The results of drag reducing tests in circle conduit indicated that polyme... |
