Poly(hydroxyethyl methacrylate) is a hydrophobic polymer which contains a hydrophilic hydroxy group. The end group functionality contains a carboxylic acid (COOH) as well as the 2-(Dodecylthiocarbonothioylthio)-2-methylpropionic acid RAFT agent moiety. This will allow for additional polymerization to generate a diblock copolymer. This RAFT agent is especially suited for the polymerization of styrene; acrylate and acrylamide monomers.
