Title (EN) HIGH INTERNAL PHASE EMULSIONS AND POROUS MATERIALS PREPARED THEREFROM
(FR) EMULSIONS A PHASE INTERNE ELEVEE ET MATIERES POREUSES PREPAREES A PARTIR DE CES EMULSIONS
Abstract:
(EN) Polyoxybutylene-polyoxyethylene sulfate-based surfactants particularly useful in preparing high internal phase emulsions. High internal phase emulsions having an internal aqueous phase of greater than 70 percent by volume and an external oil phase comprising a vinyl polymerizable monomer contain a polyoxybutylene-polyoxyethylene-based surfactant. Open-celled polymeric foams having a liquid capacity of greater than about 70 percent of its saturated volume can be prepared from such emulsions.
(FR) On décrit des tensio-actifs à base de sulfate de polyoxybutylène-polyoxyéthylène qui conviennent particulièrement pour la préparation d'émulsions à phase interne élevée. On décrit en outre des émulsions à phase interne élevée présentant une phase aqueuse interne de pourcentage volumique supérieur à 70 %, et une phase huileuse externe qui comprend un monomère pouvant subir une polymérisation vinylique et contenant un tensio-actif à base de sulfate de polyoxybutylène-polyoxyéthylène. On décrit enfin de mousses polymériques à alvéoles ouvertes ayant une capacité liquide de pourcentage volumique supérieure à environ 70 % de son volume saturé et pouvant être préparées à partir desdites émulsions.
