Abstract

A strategy for the synthesis of semi-telechelic polyethylene through the palladium diimine-catalyzed chain transfer polymerization of ethylene using various silanes as chain transfer agents is reported. Polymer molecular weight and end-group chemical structure can be tuned by varying the chain transfer agent as well as its concentration. NMR spectroscopy confirms that the silicon of the chain transfer agent is incorporated into the polymer. The stability of the catalyst toward polar monomer enables the chain transfer polymerization of semi-telechelic poly(ethylene-methyl acrylate) copolymers.
