Abstract:
A surfactant for forming stable dispersions of rosin esters compatible with elastomeric latexes which comprises a compound of the formula R.sup.1 --R.sup.2 --R.sup.3, wherein R.sup.1 and R.sup.3 are selected from the group consisting of a rosin and H, provided that R.sup.1 and R.sup.3 are not both H, and R.sup.2 is selected from the group consisting of polyethylene glycol and (polyethylene glycol)-R.sup.4 -(polyethylene glycol) wherein R.sup.4 is rosin, and wherein the polyethylene glycol has a molecular weight of from about 1,500 to about 20,000 such that the surfactant is substantially solid at room temperature.
