Advances in the Functionalized Polyolefins Synthesis and Applications

Abstract

This chapter discusses that the uses of borane containing monomers clearly present an effective and general approach in the function of polyolefins. The success of this chemistry is based on the combination of advantages, the stability of borane moiety to transition metal catalysts, the solubility of borane compounds in hydrocarbon solvents (hexane and toluene) used in transition metal polymerizations, and the versatility of borane groups, which can be transformed to a remarkable variety of functionalities and to free radicals for graft-form reactions. The functionalized polymers are very effective interfacial modifiers in improving the adhesion between polyolefin and substrates and the compatibility in polyolefin blends and composites. In general, there are two routes to the function of polymers, including direct copolymerization with functional monomers and the post modifications of preformed polymers. The chapter summarizes the new developments in the function and graft reactions of polyolefin by Ziegler-Natta catalysts and borane monomers.
