摘　　要：以1-辛烯为原料,采用淤浆聚合法合成了聚合物减阻剂(DRA)。考察了助催化剂种类及用量、外给电子体用量对所得减阻剂特性黏度的影响,并采用室内环道评价装置测定了所得减阻剂的减阻率。结果表明,淤浆聚合法工艺简便,聚合物产品的特性黏度为17.3dL/g,减阻率最高达到58.7%,与市售品相近。The oil-solvent drag reducing agent （DRA） was synthesized with slurry polymerization catalyzed by Ziegler-Natta catalyst under atmosphere pressure and 1-octene as raw material.The effects of co-catalyst type and its dosage,dosage of external electron donor on polymerization were discussed.A new process synthesizing oil-soluble drag reducing agent was suggested.The drag reducing efficiency of DRA was determined in simulative loop evaluation apparatus.The results showed that the slurry polymerization process was simple,by which drag reducing efficiency of the product DRA could reach 58.7% with the intrinsic viscosity [η] of 17.3 dL/g.
