Abstract
Novel silane compound, alkoxy cyclopentyl dimethoxysilane, is prepared by reacting cyclopentyl trihalosilane with ROH and then with methanol, or by reacting cyclopentyl trimethoxysilane with ROH, wherein alkyl in the alkoxy or R in ROH stands for an organic group selected from the group consisting of sec-butyl, tert-amyl, cyclopentyl, oxa-3-cyclopentyl, cyclohexyl and 2-isopropyl-5-methyl cyclohexyl groups. The silane compounds are useful as a catalytic component for olefin polymerization and as a silane coupling agent.
