Abstract:
A high temperature emulsion composition comprising borax and a substantially water-insoluble polymer prepared by aqueous suspension polymerizing a blend of monomers, said monomers comprising:(a) 50% to 95% by weight of the blend of at least one plasticizing alkyl acrylate monomer, said plasticizing monomer being an alkyl acrylate wherein the alkyl is selected from the group consisting of straight chain alkyl groups of from 3 to 11 carbon atoms and branched chain alkyl groups having from 5 to 11 carbon atoms;(b) 5% to 50% by weight of the blend of at least one hardening alkyl acrylate or methacrylate monomer, said hardening monomer being an alkyl acrylate or methacrylate wherein the alkyl is selected from the group consisting of alkyl groups of from 1 to 4 carbon atoms.; and(c) 0.5% to 3% by weight of the emulsion of at least one multi-ethylenically unsaturated crosslinking monomer,in an aqueous suspension comprising a water-soluble polymer component comprising at least one acrylic polymer having carboxylate functionality.
