Abstract:
A dispersion polyol, comprising:a) at least one first polyol having an average nominal functionality of from about 2 to about 8, said first polyol having an internal polyoxyalkylene block of minimally about 700 Da equivalent weight and comprising oxypropylene moieties, optionally in admixture with a minor portion with respect to said oxypropylene moieties of one or more C.sub.3 or higher oxyalkylene moieties, and about 35 weight percent or less oxyethylene moieties, and an external polyoxyalkylene block comprising minimally 50 weight percent oxyethylene moieties based on the weight of said external polyoxyalkylene block, said external oxyalkylene block constituting from about 10 weight percent to about 50 weight percent of said first polyol total weight; andb) at least a second polyol, said second polyol having an external block comprising minimally 50 weight percent oxyethylene moieties, and no internal, high oxypropylene-content block or an internal high oxypropylene-content block of no more than about 300 Da equivalent weight,said first and second polyols forming a stable liquid--liquid dispersion.
