Chemical structure water absorbency and thermal properties of poly(acrylamide-co-acrylic acid)-grafted-poly(styrene-co-methyl methacrylate)

This contribution presents the characterization of poly(acrylamide-co-acrylic acid)-grafted-poly(styrene-co-methyl methacrylate) [poly(AAm-co-AAc)-g-poly(St-co-MMA)] The chemical structure of poly(AAm-co-AAc)-g-poly(St-co-MMA) microgels was proposed. The effect of MBA contents on the degree of cross...
