Reaction of (Butadiene)zirconocene with Tris(pentafluorophenyl)borane—A Novel Way of Generating Methylalumoxane‐Free Homogeneous Ziegler‐Type Catalysts

Abstract

An active catalyst for α-olefin polymerization without addition of activator components has been discovered in the betain 2, which is formed in the title reaction shown below. Laser desorption mass spectrometry shows that B(C6F5)3-containing polymers with a molecular weight distribution typical of Ziegler catalysts are formed.
