Abstract

The free radical photopolymerizations of N,N-diallyl-N-methylamine with 3-(N,N-diallyl-N-methylammonio) propane sulfonate, and N,N-diallyl-N,N-dimethylammonium chloride with 4-(N,N-diallyl-N-methylammonio) butanoate have been studied. Reactivity ratios indicate random incorporation of the comonomers. Molecular weights range from 4.13 to 8.42 x 104 g mol-1 for the sulfobetaine-containing polymers, and from 8.9 to 21.8 x 104 g mol-1 for the carboxybetaine containing polymers. Macroscopic phase separation was observed for the sulfobetaine containing polymers with changes in pH, while the carboxybetaine containing polymer solutions remained homogeneous throughout the pH range investigated.
