Synthesis of polyolefin graft copolymers by borane approach
- Pennsylvania State Univ., University Park, PA (United States)
This paper summarizes the new developments in the graft reaction of polyolefin by borane approach. It is becoming clear that the borane groups in polyolefins are valuable intermediates which not only can be quantitatively converted to a wide range of functional groups but also can be used as initiator or co-initiator for cationic or free radical polymerizations. Some interesting graft polymers, such as PP-g-PMMA, PP-g-PVA, PP-g-polycapolactone, EP-g-PMMA, and Butyl-g-PMMA, have been synthesized with controllable compositions and molecular microstructures. Most of them would be otherwise very difficult to prepare by the other existing methods. Several methods have been developed to incorporate borane groups to polyolefins, including both direct and post polymerizations. One unique feature of borane group is its excellent stability to transition metal catalysts, such as Ziegler-Natta, and good solubility in hydrocarbon solvents. These offer the possibility to prepare borane containing polyolefins with a broad range of copolymer composition and microstructure. In terms of application, graft copolymers are useful interfacial reagents in polyolefin blends and composites.
