Stabilizers for the emulsion polymerization of olefinic monomer and comonomer systems comprise the half esters of non-ionic ethoxylates of formula R(CH2CH2O)xH in which R is C8-30 linear alkyl or C4-18 mono-, di- or tri-alkyl phenyl and R is linked to ethoxy by O, S or N and x is 4-10 with alpha , beta -ethylenically- unsaturated dicarboxylic acids, preferably maleic, citraconic, and itaconic acids. Stable, low floc, lattices having good shear are obtained useful as pressure and non-pressure sensitive adhesives. The olefinic unsaturated monomers are those of the vinyl and acrylic types. |
