SEGMENTED POLYMERS AND METHOD FOR THE SYNTHESIS THEREOF

摘要

A surface active agent contains at least one radical generator group in each of its lipophilic and hydrophilic moieties. A water-in-oil dispersion or oil-in-water dispersions contains a first polymerisable monomer dissolved in the oil phase and a second monomer dissolved in the oil phase and a second monomer dissolved in the aqueous phase. A surface active agent as defined above is dispersed across the interface of the oil phase and the aqueous phase with its lipophilic moiety well solvated by the oil phase and its hydrophilic moiety well solvated by the aqueous phase. A segmented polymer comprising such a surface active agent having at least one lipophilic polymer segment attached to its lipophilic moiety and at least one hydrophilic polymer segment attached to its hydrophilic moiety can be formed from the dispersion.
