| Zusammenfassung: | The product and process is directed to polymerizing second stage ethylenically unsaturated monomers within an aqueous dispersion of a preformed epoxy based resinous material comprising a mixture of graft epoxy polymer containing grafted addition polymer grafted to the epoxy backbone, ungrafted epoxy polymer, and ungrafted addition polymer uniformly dispersed in water wherein the second stage monomers are polymerized in the presence of at least 0.1% of benzoin derivative reducing agent based on monomer weight in combination with a peroxide polymerization initiator. |
