Production of polyolefin

Abstract

Abstract PURPOSE:To obtain a high-purity and high-molecular weight polyolefin at normal temperature by polymerization of an olefin in the presence of a catalyst consisting mainly of an oxygen-contg. titanium compound and reaction product from water and organoaluminum compound. CONSTITUTION:The objective polyolefin can be obtained by polymerization of an olefin (pref. 2-10C alpha-olefin) in the presence of a catalyst of novel composition consisting mainly of (A) an oxygen-contg. titanium compound (e.g. tetramethoxytitanium, diisopropoxytitanium dichloride) and (B) an aluminoxane, a reaction product from water and an organoaluminum compound (e.g. trimethylaluminum, triisobutylaluminum). USE:The polyolefin thus obtained is useful as a raw material for blend bases, adhesives, electrical insulating materials, and various molded articles.
