ABSTRACT:
Improved butyl rubber-hydrocarbon resin latex compositions are prepared by emulsifying a solution of butyl rubber and a hydrocarbon resin in a one-step process wherein the emulsifying agent is the sodium salt of the sulfate ester of nonylphenoxypoly(ethyleneoxy) ethanol. The films formed therefrom exhibit improved properties over compositions prepared from blends of latices of butyl rubber and hydrocarbon resins.
