摘要: 利用高活性聚异丁烯和两种有机硅化合物,通过硅氢加成反应合成了聚异丁烯聚硅氧烷和聚异丁烯三硅氧烷两种产物,并对两种产物进行了对比分析。结果表明,聚异丁烯聚硅氧烷的表观黏度高于聚异丁烯三硅氧烷的表观黏度,当在大庆原油中加入质量分数为0.6%产物时,聚异丁烯聚硅氧烷可使大庆原油黏度降低34.6%,聚异丁烯三硅氧烷可使大庆原油黏度降低64.8%。聚异丁烯聚硅氧烷的热性能高于聚异丁烯三硅氧烷。

Abstract: Using high activity polyisobutylene and two kinds of organic silicon compound,polyisobutylene polysiloxane and polyisobutylene trisiloxane were synthesized by hydrosilylation. Contrastive analysis was then conducted on them. The results suggested that the apparent viscosity of polyisobutylene polysiloxane was higher than that of polyisobutylene trisiloxane. When 0.6% of product was added,the viscosity of Daqing crude oil decreased 34.6% by polyisobutylene polysiloxane,and 64.8% by polyisobutylene trisiloxane. Thermal property of polyisobutylene polysiloxane was better than that of polyisobutylene trisiloxane.

Key words: high activity polyisobutylene, hydrosilylation, apparent viscosit, thermal property
