Amphiphilic copolymers useful especially as emulsifiers
The invention concerns copolymers of the poly(styrene)-poly(ethylene-butylene)-poly(styrene) type wherein the central poly(ethylene-butylene) sequence has been modified by chemical grafting of hydrophilic groups to make them amphiphilic. The invention also concerns a method for preparing said novel...
