## Abstract A new strategy was used to prepare an interpenetrating polymer network of two stimuliβresponsive polymers, a thermosensitive poly __N__βisopropylacrylamide (PNIPAAm) and a pH sensitive poly(acrylic acid) (PAAc) grafted onto poly(propylene) (PP) films (PPβ__g__βPAAc). Three consecutive s
## Abstract Interpenetrating polymer network (IPN) hydrogels composed of poly(2βethylβ2βoxazoline) (PEtOz) and chitosan (CS) were prepared with radical polymerization and were characterized for their swelling properties. Sample OC11 (hydrogel weight ratio PEtOz/CS = 1/1) swelled more than samples O
