Abstract: | Blocked copolymer of acrylic acid-methyl methacrylate with controlled molecular architecture were prepared by reversible addition chain fragmentation polymerization and were characterized by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (1H NMR), and gel permeation chromatography (GPC) for structural evaluation. The neutralized copolymers were evaluated for the critical micelle concentration (CMC), hydrophilic lipophilic balance (HLB) and were utilized as polymeric emulsifier cum macro RAFT initiator for the synthesis of acrylic binder. The structure properties of the emulsifier were evaluated correlating with the film properties. |
