  • Graft copolymers and the method of their preparation
    Patent number: 4584354
    Abstract: Graft copolymers are formed having a backbone formed by monomeric units, selected from the group of vinyl monomers comprising acrylates, methacrylates, acrylamide, styrene and N-vinyl-2-phyrrolidone, and side branches formed by 10-80 wt. % of oligourethanes based on aliphatic, aromatic and alkylaromatic diisocyanates and low-molecular-weight diols with 2-4 carbon atoms in the molecule. The graft copolymers are prepared in two steps: the first step consists in the synthesis of oligourethane with the terminal unsaturated group; the second step is the radical copolymerization of this oligourethane with the above vinyl monomers.
