Abstract: Method for polymerization in emulsion of at least a polymerizable monomer by radical means in the presence of a stable free radical and an emulsifier is claimed. The emulsion comprises an aqueous liquid phase containing at least 50 wt.% water and an organic liquid phase containing more than 50 wt.% monomer(s). Independent claims are also included for: (i) polymer particles comprising polymerized units of at least two monomers; (ii) an assembly of these particles; and (iii) a latex comprising this assembly.

Abstract: The invention concerns a monoconstituent system based on polymer of size ranging between 50 and 500 nm crosslinking at room temperature during the film formation process. The crosslinking is obtained by the presence of a hydrated acetal and/or an aldehyde function which are self-crosslinking in an acid medium.

Abstract: L'invention décrit un système monocomposant à base de particules de polymère de taille comprise entre 50 et 500 nm réticulant à température ambiante au moment de la filmification. La réticulation est obtenue grâce à la présence de fonctions acétal et/ou aldéhyde hydraté qui s'autoréticulent en milieu acide .
