Abstract
Copolymers prepared by a reaction of (1) an unactivated olefin, (2) an activated olefin, and (3) a hydroxyl functional activated olefin and/or a hydroxyl functional unactivated olefin are described. The copolymers have a backbone of polar vinyl monomers and non-polar alkene monomers, with pendant hydroxyl functional groups. The copolymers are well suited for optically clear, pressure sensitive, polyurethane and/or barrier adhesives.
