1-ブテンポリマーの製造方法
Document Type and Number:
Japanese Patent JP2006509059
Kind Code:
A
Abstract:
A process for obtaining 1-butene polymers optionally containing up to 30% by mol of ethylene, propylene or an alpha-olefin of formula CH2=CHZ, wherein Z is a C3-C10 alkyl group s, comprising the step of contacting under polymerization conditions 1-butene and optionally ethylene, propylene or said alpha-olefin, in the presence of a catalyst system obtainable by contacting: a) a metallocene compound of formula (I): R<3> R<2 >R<4 >0 R~ Rs MXp LLR<6> R<5 >R' O R<2 >R<4 >(I) wherein: M is an atom of a transition metal belonging to group 3, 4, 5, 6 or to the lanthanide or actinide groups in the Periodic Table of the Elements; p is an integer from 0 to 3; X, is a hydrogen atom, a halogen atom, or a hydrocarbon group; R<1> is a hydrocarbon group; RZ, R<3> and R<6> are hydrogen atoms or hydrocarbon groups; R<4> and R<5> join to form a condensed saturated or unsaturaded 4-7 membered ring; and L is a divalent bridging group; and b) an alumoxane or a compound able to form an alkylmetallocene cation.
