New vinyl-polyether alcohol derivs. - useful as surfactants and intermediates for polyether sulphonate(s), prepd. by reacting polyether alcohol with vinyl oxirane
Vinyl-polyetheralcohols of formula R(0A)n0CHzCH0HCH=CHz (I) are new. R = 1-25C alkyl, 2-25C alkenyl or up to 20C alkaryl; A = 2-4C 1,2-alkylene; n = 1-20. Also new is prodn of polyethersulphonates R(0A)n0CHzCH0HCHzCHzS03H (III) by reacting (I) with an alkali metal or NH4 sulphite, hydrogen sulphite or disulphite or mixt. M = H, alkali metal or NH4. - A = CH2CH2; R = 8-20C alkyl; n = 2-15.
