  • Patent number: 6448330
    Abstract: A highly stable aqueous emulsion of a polymer predominantly comprised of units of at least one monomer selected from acrylate esters, methacrylate esters, styrenic monomers and diene monomers, which is dispersion-stabilized with a water-soluble compound having a molecular weight of at least 300 and an alcoholic hydroxyl group; characterized by having an average particle diameter of 0.05-5 &mgr;m, a calcium chloride chemical stability index of at least 20 and a surface tension of at least 45 mN/m as measured at a solid content of 30 wt. %. The aqueous emulsion is produced by polymerizing a monomer or monomers in the presence of an alcohol and a polymerization initiator generating a peroxide free-radical in an aqueous medium, while the monomer or monomers and the alcoholic hydroxyl group-containing water-soluble compound are incorporated continuously or intermittently into a polymerization system.
