| abstract | 1455495 Polymer blends; polyurethanes; and foams thereof IMPERIAL CHEMICAL INDUSTRIES Ltd 3 Jan 1975 [28 Jan 1974] 03829/74 Headings C3C C3P and C3R Dispersions of a polymer of one or more ethylenically unsaturated monomers in a hydroxyl-ended polymer are prepared by (i) polymerizing said monomer(s) in an inert solvent under otherwise conventional conditions, (ii) adding a hydroxyl-ended polymer to the polymerisate/solvent mixture, and (iii) removing the solvent by evaporation or distillation, e.g. in a thin film evaporator. In examples, acrylonitrile and acrylonitrile/styrene polymers are made in chlorobenzene; and the hydroxylended polymer added thereto is an ethylene oxide-tipped oxypropylated glycerol, or polyethylene adipate. The dispersions prepared above are used in the manufacture of polyurethanes by reaction with polyisocyanates. Example 4 illustrates the preparation of a foamed polyurethane from a dispersion of acrylonitrile/styrene copolymer in an ethylene oxide tipped polyoxypropylene glycerol and a polyisocyanate by otherwise conventional means using trichlorofluoromethane as blowing agent. |
