Abstract

PURPOSE: To provide an aq. dispersion which exhibits excellent dispersion stability when said dispersion is diluted or left to stand, and is useful as a dispersion-stabilizing aid for adhesives, pressure-sensitive adhesives, rewetting agents, suspension polymn. or emulsion polymn., containing a water-insouble PVA and a water-souble PVA in a specified ratio.
CONSTITUTION: There is provided an aq. dispersion consisting of a water-insoluble PVA (A) having an average saponification degree of 20W65mol% and an average polymn. degree of 1,000 or below, a water-soluble PVA (B) (e.g. PVA having an average saponification degree of 65mol% or above and an average polymn. degree of 100W3,000) and water (C) in a weight ratio of (A)/(B) of 7 or above an of (B)/(A)+(B) of 0.01 or above. This dispersion can be produced by adding powders of components A and B to water, if desired, under heating, or by adding powder of component A to an aq. soln. of component B.
EFFECT: The stability of the produced dispersion is not changed, even when the dispersion is left to stand for 30 days or longer. The dispersion can be produced by a simple method.
