The present invention relates to a process of making aqueous dispersions of copolymers, for example based on conjugated, aliphatic dienes and vinyl aromatic compounds. It relates also to the emulsions polymers obtained thereby, and to the use thereof as binders for the coating of paper. The invention also related to a coated paper having a coating comprising the emulsion copolymer. The process involves using at least two emulsifiers.
La présente invention concerne un procédé de préparation de dispersions aqueuses de copolymères, à base par exemple de diènes aliphatiques conjugués et de composés aromatiques vinyliques. L'invention concerne également les polymères en émulsion ainsi obtenus et leur utilisation en tant que liants pour le couchage du papier. L'invention concerne en outre un papier couché dont le couchage comprend le copolymère en émulsion. Le procédé implique l'utilisation d'au moins deux émulsifiants.
