ABSTRACT OF THE DISCLOSURE The present invention relates to a method of purifying readily polymerisable high boiling vinyl monomers, in particular the acrylates and methacrylates of alkylene oxides and their ether and ester derivatives to obtain pure water white esters. The process involves flash evaporation of the preheated esters followed by condensation in the presence of polymerisation inhibitors under specific conditions. The purified esters thus produced find use either as such or in the form of their copolymers in coatings, enamel paints, weather resistant finishes, adhesive compositions, as plasticizers, as lubricants for cellulose films and fibres, in magnetic tape recording media and as oil additives.
