Abstract
A method to fabricate polyolefin polymer with hydroxyl functional group is taught. The method comprises following steps: (1) blending a polar solvent, an α,ω-alkyenol compound and a trialkyl halosilane compound to form an trialkyl-siloxane group protected co-monomer; (2) copolymerizing the trialkyl-siloxane group protected co-monomer with an α-olefin monomer to form a copolymer with side chain trialkyl-siloxane group protectors in presence of a metallocene catalyst and co-catalyst mixture; and (3) hydrolyzing the copolymer with an acid to form the polyolefin polymer with at least one hydroxyl functional group.
