Abstract
A hydrophilic or hydrophobic polyurethane containing on average per molecule at least one olefinically unsaturated structural unit selected from the group consisting of pendant, internal, and terminal, acyclic and cyclic terpene units; graft copolymers of the polyurethane with olefinically unsaturated monomers, processes for preparing the polyurethane and the graft copolymers, and their use for preparing coating materials, adhesives, and sealing compounds.
Claims21
A graft copolymer comprising a (co)polymerization product of at least one olefinically unsaturated monomer and at least one hydrophilic or hydrophobic polyurethane containing on average per molecule at least one olefinically unsaturated terpene unit, wherein the terpene unit is at least one of pendant, internal, and terminal, and wherein the terpene unit is at least one of an acyclic terpene unit and a cyclic terpene unit.
