EMULSIONS STABILIZED BY FORMING A POLYMERIC THIN FILM AT THE INTERFACES OF OIL PHASE AND WATER PHASE

摘要

The present invention relates to a stabilized emulsion to form a polymer thin film produced by the oil / water interface using the amphiphilic polymer. And than use specifically, the emulsion is 1) the oil phase, 2) an aqueous solution phase, and 3) parent as a distributed system consisting of a polymer, in particular an amphiphilic polymer having a having polycaprolactone as the hydrophobic block polyethylene glycol hydrophilic block It characterized by forming a polymer thin film at the interface of the emulsion. These amphiphilic polymers can have a characteristic hydrophobic block, forming a polymer thin film solidified without being dissolved in the oil phase has a new mechanism for the interfacial stability distribution at the interface.
