## Abstract In this study, pH‐responsive inulin hydrogels were prepared by radical copolymerization of methacrylated inulin (MA‐inulin) with acrylic acid (AAc) in aqueous solution using ammonium peroxydisulfate (APS) and __N,N,N__′__,N__′‐tetramethylethylenediamine (TMEDA) as an initiation system.
Novel pH-sensitive physically crosslinked hydrogels were synthesized by grafting D,L-lactic acid (LA) onto the amino groups in chitosan (CS) without a catalyst. The structures of these graft copolymers were analyzed by FTIR and X-ray measurements. Degree of substitution, side-chain length, and yield
