Abstract: The performance of isoprene rubber synthesized by the titanium catalyst is comparable to that of natural rubber. The paper is aimed to introduce the domestic and abroad developments of cis-1,4-polyisoprene rubber，and to summarize the influence factors of kinetic behavior for the polyisoprene polymerization and the content of cis-1,4-polyisoprene configuration in the microstructure of rubber synthesized by titanium catalyst. An overview on the synthesis methods of cis-1,4-polyisoprene by titanium catalyst is conducted，and the developing trend for titanium cis-1,4-polyisoprene rubber is prospected. It can be concluded that developing a cheap titanium catalysis system is an inevitable trend in the synthesis of isoprene rubber，developing titanium high cis-1,4-polyisoprene should be the prime choice for polyisoprene synthesis industry. Some existent problems and possible research subjects for the further improvement of synthesis cis-1,4-polyisoprene are suggested and discussed.
