Zusammenfassung:	The present disclosure is directed to an ultra-high solids emulsion comprising a plurality of multiphase polymer particles, in which the multiphase particles comprises an acrylic-based copolymer derived from monomers comprising an alkyl methacrylate; an alkyl acrylate; a hydroxyalkyl acrylate; at least one or more acids; a vinyl aromatic compound; and a vinyl ester or vinyl lactam, a copolymerizable surfactant, at least one or more alkylphenol ethoxylate (APE) free nonionic surfactants, and at least one or more APE free anionic surfactants in aqueous medium in the presence of an initiator and a buffer. Additionally, methods for preparing such ultra-high solids emulsion and applications of such emulsion in coatings and adhesives are disclosed. La présente invention concerne une émulsion à teneur ultra-élevée en solides comprenant une pluralité de particules polymères multiphases, les particules multiphases comprenant un copolymère à base d'acrylique dérivé de monomères comprenant un méthacrylate d'alkyle ; un acrylate d'alkyle ; un acrylate d'hydroxyalkyle ; au moins un ou plusieurs acides ; un composé aromatique vinylique ; et un ester vinylique ou un lactame vinylique, un tensioactif copolymérisable, au moins un ou plusieurs tensioactifs non ioniques exempts d'éthoxylate d'alkylphénol (APE) et au moins un ou plusieurs tensioactifs anioniques exempts d'APE dans un milieu aqueux en présence d'un initiateur et d'un tampon. De plus, l'invention concerne des procédés de préparation d'une telle émulsion à teneur ultra-élevée en solides et des applications de ladite émulsion dans des revêtements et des adhésifs.
