  • Polyurethanes containing triazine or both triazine and oxazoline, triazine and imino carbamate or triazine and other N-heterocyclic groups
    Patent number: 4699933
    Abstract: The present invention is directed to polyurethane compositions containing triazine or both triazine and oxazoline or imino carbamate groups which are prepared by reacting:1.(a) at least one alkoxylated hydroxy aromatic oligomer containing at least one triazine group, or(b) at least one alkoxylated hydroxy aromatic oligomer containing at least one triazine group and at least one oxazoline group, or(c) at least one alkoxylated hydroxy aromatic oligomer containing at least one triazine group and at least one imino carbamate group, or(d) at least one alkoxylated hydroxy aromatic oligomer containing at least one triazine group and at least one other N-heterocyclic group, or(e) a mixture of the above and2. at least one material having more than one isocyanate group per moleculewherein the components are employed in proportions which provide a ratio of isocyanate groups to hydroxy groups of from about 0.05:1.0 to about 10.0:1.0, preferably from about 0.95:1.0 to about 1.5:1.0.
