Abstract
This invention relates to stable aqueous dispersions of film-forming addition polymer. Novel aqueous dispersions comprise polymer which is a copolymer of amphipathic and non-amphipathic monomer. The amphipathic monomer has an HLB value of at least 8, the hydrophilic component thereof is non-ionic, and the lipophilic component has a molecular weight of at least 100, comprises at least one ethylenic double bond but has no acrylyl or methacrylyl structure. The polymer comprises up to 80% by weight of amphipathic monomer. The dispersions are useful as components of such compositions as surface coatings and adhesives.
