NEW DIBLOCK COPOLYMERS CONSISTING OF POLYOLEFIN AND FUNCTIONAL POLYMER SEGMENTS

摘要

Diblock copolymers comprising a polyolefin segment and a functional polymer segment and having the structural formula: (Polyolefin Segment)-f-(Functional Polymer Segment), wherein f is a chemical linkage, such as an ether, ester or amide group linkage, have been prepared by contacting a polyolefin having a terminal borane group with a free radical polymerizable monomer or by reacting a functionalized polyolefin with a cyclic monomer capable of undergoing ring opening polymerization using the functional group on the functionalized polyolefin as the initiator for the ring opening polymerization. The diblock copolymers are useful as interfacial materials for improving the interaction between polyolefins and other materials.
