Aqueous emulsions of high softening point hydrocarbon resins and process for preparing the same

Abstract

An aqueous petroleum resin emulsion is realized by the slow addition of part of the water with vigorous agitation to a resin blended with up to 10 weight percent resinplast and in the presence from 3 to 10 weight percent of an emulsifier until inversion and thereafter adding the balance of the water at low agitation and thereafter cooling said emulsion to a temperature at least 20.degree. C. below the softening point of the mixture of emulsifier, resin and resinplast prior to terminating agitation.
