Swelling parameters such as the start-time of the hydrogel-formation, initial rate of swelling, swelling rate constant, equilibrium swelling, and equilibrium water content (EWC) are determined for polymers/APTS/water systems with certain copolymer/crosslinker ratios (1.4/1 and 9/1). The formation of a hyperbranched network structure by the fragmentation of the side-chain reactive groups in the systems studied has also been confirmed by the Fourier Transform Infrared (FTIR) method.eninfo:eu-repo/semantics/openAccess-aminopropyltriethoxysilanecrosslinkinghydrogelmacromolecular reactionpoly(MA-alt-AAm)poly(VA-co-MA-co-AAm)swelling parametersSynthesis and swelling peculiarities of new hydrogels based on the macromolecular reaction of anhydride copolymers with -aminopropyltriethoxysilaneArticle44390391110.3109/21691401.2014.998829257616272-s2.0-84970021274Q1WOS:000376136500020Q1
