Process for the preparation of addition products of expoxides and hydroxylated compounds, characterised by the fact that it comprises the reaction of an epoxide, selected from the group consisting of alkylene oxide and epichlorhydrin, and of a hydroxylated compound selected from the group consisting of an alcohol, an alkyleneglycol monoalkylether, a phenol compound and water, in a quantity such that the ratio of the hydroxylated compound/epoxide is comprised between 2 and 20 by weight, the reaction being carried out in a homogeneous liquid phase, at a temperature between 40.degree. and 250.degree. C., in the presence as catalyst selected from the group consisting of (a) tetra-alkylammonium triflate and (b) a trifluoromethanesulfonic acid salt of a metal selected from the group consisting of an alkali metal, a metal belonging to Group, II of the Periodic Table of Elements, aluminium, cobalt, nickel, zirconium and tin, in such a quantity that the catalyst concentration in the reaction mixture is comprised between 1 and 100 ppm by weight.
