Title
(EN) PREPARATION OF POLYMER LATEXES
(FR) PREPARATION DE LATEX EN POLYMERE
Abstract
(EN)
This invention relates to the preparation of surfactants with reactive organic counterions, and the use of these surfactants as emulsifiers and/or stabilizers in surfactant-mediated heterophase polymerization processes e.g. emulsion polymerization; miniemulsion polymerization for the preparation of polymer latexes. The invention further relates to the preparation of coatings with improved water resistance, and reduced surfactant mobility thus reducing the problem of film detachment from the substrate known as 'blooming'; and reducing film whitening upon prolonged immersion in water (problem referred as 'blush').
(FR)
L'invention concerne la préparation de surfactants avec des contre-ions organiques réactifs et leur utilisation comme émulsifiants et/ou stabilisateurs dans des processus de polymérisation hétérophasique provoquée par un surfactant, soit par exemple une polymérisation par émulsion ou par mini-émulsion pour la préparation de latex en polymère. L'invention concerne aussi la préparation de revêtements présentant une hydrorésistance améliorée et une mobilité réduite du surfactant, réduisant ainsi le problème des films qui se détachent du substrat, connu sous le terme d' 'efflorescence' ; et réduisant le blanchiment des films après immersion prolongée dans l'eau (problème connu sous le terme de 'voile').
