Viscosity stabilized dispersions
Abstract
Abstract The present invention is directed to a composition comprising: (a) a dispersion of a polyurea and/or polyhydrazodicarbonamide in a relatively high molecular weight organic compound containing at least two hydroxyl groups, wherein the concentration of the polyurea and/or polyhydrazodicarbonamide is from 1 to 40% by weight of the dispersion, (b) from 2 to 10% by weight of water based on the weight of component (a), and (c) from 3 to 10% by weight based on the weight of components (a) and (b), of a sulphonate diol corresponding to the formula: <IMAGE> wherein A and B may be the same or different and represent a difunctional aliphatic hydrocarbon radical containing from 1 to 6 carbon atoms; R represents hydrogen, an aliphatic hydrocarbon radical containing from 1 to 4 carbon atoms, or a phenyl radical; X(+) represents an alkali metal cation, or an ammonium group which may be substituted; n and m represent the same or different numbers of from 1 to 30; o and p each represent 0 or 1; and q represents 0, 1 or 2.
