초록

A block copolymer of a hydrophobic block of one or more hydrophobic monomers and a hydrophilic block of one or more hydrophilic monomers is prepared by polymerizing a hydrophobic monomer to prepare the hydrophobic block, using a free radical polymerization process using a stable free radical agent, preserving a stabilized active polymerization site on the hydrophobic block; adding a hydrophilic monomer to the stabilized active hydrophobic block; and further reacting the mixture to effect polymerization of the hydrophilic monomer. The polymerization of th...
