摘要: The simultaneous gravimetric and dilatometric techniques have been used to study the kinetics of aqueous free radical crosslinking copolymerization acrylamide (AAm) N,N'-methylenebisacrylamide (MBA) at different crosslinker ratios, reaction temperatures. In this study, gel properties were investigated using swelling measurements microscopic techniques. Based on data, it was proposed that deviation point results technique from those one can be a new criterion for point. monomer conversion equilibrium ratio hydrogels measured as function time. Experimental data showed an inverse dependence critical concentration. As MBA/AAm decreased 0.1 wt%, product appearance changed. addition, effects temperature rate studied. At higher temperatures, reached it...
