Polyolefin-block-polar-polymer block copolymer ( POBP)

consisting of both nonpolar/unfunctionalized polyolefin block(s) and polar/functional polymer block(s) that are covalently bonded together

have drawn much attention due to their unique structure and performance characteristics. The traditional use of POBP as a polyolefin and other materials (polar polymer

e.g. ) of the compatibilizer

in recent years

POBP find new applications in emerging research fields

including porous membrance

functional hybrid nanomaterials and solid polymer electrolyte

etc. Two main types of methods are employed in preparation of POBP : (1) Mechanism transformation from coordination polymerization to other polymerizations

that is

to initiate polymerization of polar monomer using polyolefin macroinitiator prepared by coordination polymerization; (2) Coupling reactions between reactive/functional end-groups of polyolefins and polar polymers. Herein we review the very recent progress on POBP

with an emphasis on the newly developed methods of POBP and emerging applications of POBP on the horizon.
