Claims
- 1. A method for the production of a hydrocarbon resin in water emulsion comprising the sequential steps of admixing from 3 to 10 parts by weight of an emulsifier of the class consisting of nonionic polyoxyethylene alkyl aryl ether, anionic alkyl aryl sulfonate and mixtures thereof with from 80 to 97 parts by weight resin having a ball and ring softening point in excess of 85.degree. C. and from 0 to 10 parts by weight of a resinplast, heating said admixture to about 120.degree. C., slowly adding water heated to about 100.degree. C. to said heated admixture with stirring over a period of at least 20 minutes and until inversion occurs, and then adding sufficient additional water with agitation to provide an aqueous emulsion containing from 30 to 75 weight % water and thereafter cooling to a temperature less than about 20.degree. C. below the softening point of the mixture of emulsifier, resin and resinplast prior to terminating agitation.
- 2. A method according to claim 1 wherein said stirring is vigorous agitation and the temperature of said admixture is at least 5.degree. C.-10.degree. C. greater than its softening point prior to inversion.
