Abstract
A product and processes comprising urethane polymer and at least one copolymer from a hydrophobic ethylenically unsaturated C-Colefins copolymerized with polar monomers such as acrylates. One process optionally utilizes an acid source to modify/catalyze the reactivity of the polar monomer and/or radically activated repeat unit from the polar monomer to promote incorporation of the ethylenically unsaturated olefin. Other processes vary depending on which polymer if formed and/or dispersed first. The hybrid copolymer shows excellent adhesion to a variety of polymeric and/or polar substrates such as polyolefins, acrylate coatings, wood, etc.
