液体聚异戊二烯的合成与应用研究进展

Review on synthesis and application of liquid polyisoprene

固态橡胶具有较高的分子量、强度及伸长率,在工业和日常生活中均得到广泛应用.然而,固态橡胶黏度较高,在应用中往往必须引入添加剂.而液体聚异戊二烯是一种液态橡胶,可以作为固态橡胶的软化剂;得益于其特殊的形态和性能,液体聚异戊二烯可望在多方面得到应用.对液体聚异戊二烯的合成与应用进行了评述.

Since solid rubbers usually possess high molecular weight as well as good strength and elongation rate, they are widely applied in industry and our daily life. However, solid rub bers often possess high viscosity and cannot be well applied in some fields unless they are doped with proper additives. Fortunately, liquid polyisoprene, a liquid rubber, can be adopted as a softener of solid rubbers. This makes it feasible for liquid polyisoprene possessing special state and properties to find promising application in many fields. The synthesis and application of liquid polyisoprene are reviewed.
