STUDIES ON MICROBLOCK STRUCTURE OF AM/DMBAC CATIONIC COPOLYMERS
|
Abstract:
The surface activity of cationic DMBAC ( dimethyl methacryloyloxyethyl benzyl ammonium chloride) was revealed by measuring surface tension and estimating of critical micelle concentration ( CMC). The copolymerization of acrylamide ( AM) and DMBAC was studied in aqueous solution at above and below CMC of DMBAC,respectively. The reactivity ratios r1 and r2 were determined by the Fineman-Ross method. IR and 1H-NMR spectra afford information about polymer structure. The compositions of copolymers were calculate...
