FIELD: polymer materials. ^ SUBSTANCE: invention, in particular, relates to carbonate, hydroxide, silicate, sulfate, and similar types of mineral fillers. Method of treating mineral fillers with particular granulometric composition using treating agents of the organic phosphate type comprises deagglomeration and, if necessary, selection stages. In order to prepare polyurethanes, especially foamed ones, a mixture of organic phosphate-treated mineral fillers with a polyhydric alcohol is used. Foamed polyurethanes are prepared by foaming without or with associated pore formation. Composite polyurethanes may also contain organic phosphate-treated filler. ^ EFFECT: increased dispersibility of mineral filler in polyhydric alcohol. ^ 33 cl, 9 tbl, 4 ex
