Patent ID: 6900265

Claim:
A coating adhesive, sealant or elastomeric material comprising a polymer latex comprising: a) at least one monomer unit; and b) at least one anionic surface active agent unit; wherein the monomer unit is derived from an ethylenically unsaturated monomer; the surface active agent is derived from a polymerizable surface active agent in the form of an amine salt comprising: i) at least one acid, wherein the acid is a fatty phosphate acid ester; and ii) at least one nitrogenous base having the formula: wherein R 1 , R 2 and R 3 are independently hydrogen or organic groups containing an ethenylene group, provided that at least one of the R 1 -R 3 groups is a straight or branched chain alkyl group containing 1-8 carbon atoms and an ethenylene functionality; and the ethylenically unsaturated monomer and the polymerizable surface active agent have polymerized to form the polymer.
