| abstract | Polyvinyl containing copolymers are prepared by reacting an organic polymer in which all carbon to carbon bonds are saturated and having a molecular weight in excess of 1000 and containing at least one terminal isocyanate group, with a hydroperoxide to convert the isocyanate group to a peroxy/carbamate group and either simultaneously or in a second step polymerizing at least one ethylenically unsaturated monomer using the peroxy/carbamate as the polymerization catalyst to form a copolymer containing at least one polyvinyl chain connected to the polymeric residue of the peroxy carbamate by a urethane group. Block copolymers containing two polyvinyl chains connected via terminal urethane groups to the residue of the organic polymer, which residue is at least 20% by weight of the block copolymer, are claimed per se. The reaction of the isocyanate groups with the hydroperoxide may be catalyzed by means of a tertiary amine. The organic polymers specified are the reaction products of polyesters or polyethers with polyisocyanates, the hydroperoxides are t-butyl, tetralin, phenylcyclohexane, cumene, di-isopropylbenzene, p-menthane and pirane hydroperoxides and 2,5-dimethylcyclohexane-2,5-dihydroperoxide; and the unsaturated monomers are vinyl chloride, alcohol and acetate, methyl vinyl ketone, styrene, vinylidene chloride, methyl and ethyl acrylates, chloroacrylic esters, methacrylic esters, acrylonitrile, methacrylonitrile, butadiene, isoprene, chloroprene, and tetraethylene glycol dimethacrylate. |
