通过本体聚合在催化剂TiCl4/Al(Et)3作用下合成α烯烃减阻剂,通过红外光谱(IR)和X射线衍射(XRD)对聚合物进行结构分析,研究了合成聚合物影响因素对减阻聚合物特性粘度的影响.结果表明当粘度达到8.8 dl/g时减阻率可达到43.1%,即在一定范围内减阻率与粘度成正比.此时合成减阻剂的最优条件为3?C,主催化剂(TiCl4/MgCl2)、助催化剂(Al(Et)3)和二苯基二甲氧基硅烷(DDS)用量分别是0.085克,0.14毫升和0.04毫升.

Catalystα-olefin DRA (Drag Reducing Agent) synthesized by bulk polymerization TiCl4/Al(Et)3 use IR and XRD to study the structure of the polymer. This study is about the polymer operation condition effect of the drag reducing polymer intrinsic viscosity. The result indicate viscosity could reach 8.8 dl/g drag reducing effciency can reach 43.12%which means in certain range drag reducing effciency is proportional to viscosity. The optimal operation conditions are at-3?C, the dosages of the main catalyst(TiCl4/MgCl2), co-catalyst(Al(Et)3), and diphenyldimethoxysilane(DDS) are 0.085 g, 0.14 ml and 0.04 mL, respectively.
