  • Patent number: 4775715
    Abstract: Cationic polyvinyl alcohol is prepared by blending polyvinyl alcohol under high shear conditions, at 0.degree.-100.degree. C., with a small amount of water, a small excess of base, and a quaternizing agent containing a halohydrin radical and a quaternary ammonium group. The quaternization proceeds with acceptable conversions of about 35 to well over 50%. The quaternized polyvinyl alcohol has many applications, including use as a flocculating agent, as a stabilizing colloid, and in adhesive formulations.

  • Patent number: 4294738
    Abstract: Oligomer solution, process of increasing the water-miscibility of the oligomer solution, one- and two-part coating solutions containing the oligomer solution, and substrates coated with the coating solution, said oligomer solution being miscible with at least 12 wt % of water, based on non-volatile ingredients, and consisting essentially of:(a) about 50 to about 94 wt % of an oligomer having a degree of polymerization (DP) of about 10 to about 50, for example, an oligomer of vinyl acetate, hydroxyethyl acrylate, and a C.sub.1-8 alkyl acrylate;(b) 0 to about 30 wt % of a polyalkylene ether glycol having a molecular weight of about 400 to about 1300; and(c) 0 to about 20 wt % of a water-miscible solvent,with the sum of the weight percentages being 100%.
