Kinetics and Colloidal Stability of Raft/Miniemulsion Polymerization of MMA Using Comblike Polymeric Surfactants

摘要

Three comblike amphiphilic copolymers have been prepared via conventional free-radical random copolymerization of [2-(acryloyloxy)ethyl]trimethylammonium chloride (AETMAC), and stearyl methacrylate (SMA) with different feed ratios in ethanol solution. Subsequently, these copolymers were used as polymeric surfactants in the RAFT/miniemulsion polymerization of methyl methacrylate (MMA). The effects of the composition and amount of the polymeric surfactants on the controlled/living polymerization of MMA such as kinetics and colloidal stability in the systems have been investigated.
