摘要
Process of preparing anionic polyurethane latexes without the addition of a foreign emulsifying surface active agent comprising rendering the basic polyester or polyether constituent of the latex intrinsically emulsifiable or dispersible in water by incorporating an anionic functional group in the chain thereof and reacting this basic constituent with a diisocyanate in order to obtain a prepolymer which is then emulsified in water.
