Recent Advances in the Preparation of Polybutene-1

Polybutene-1 is mainly used in the manufacture of pipe area instead of metal pipe because of the good properties such as thermostability,creep resistance,pressure resistance,environmental stress,crack resistance,flammability resistance,grinding resistance,superior processibility and environmental protection and so on.The recent progress both in Ziegler-Natta catalysts and metallocenes for preparing polybutene-1 is reviewed in this paper including 31 literatures.In the case of Ziegler-Natta catalysts,we introduce mainly the effect of electron donors and other reaction conditions on the structure of polybutene-1 as well as the preparation of Ziegler-Natta catalysts.In the meantime,we focuse on the influence of metallocene structure on the structure of polybutene-1.Furthermore,our opinion on the development of polybutene-1 in our country is put forward.
