## Abstract **Summary:** Novel temperature sensitive poly(__N__โisopropylacrylamideโ__co__โacryloyl betaโcyclodextrin) (P(NIPAโ__co__โAโCD)) hydrogels with fast shrinking rates were prepared by radical polymerization of NIPA, AโCD and crosslinker in a mixture of water/1,4โdioxane as solvent. Becaus
A fundamental study about the characterization of a poly(Nisopropylacrylamide), poly(NIPAM), microgel, cross-linked with N,N -methylene bisacrylamide (BA), has been carried out. The anionic charge of this system was increased by copolymerization with 2-acrylamido-2methylpropanesulphonic (AMPS) acid.
Monodisperse poly(N-isopropylacrylamide-co-acrylic acid) hydrogel microspheres were prepared by a membrane emulsification method using membranes of pore diameters of 0.33, 0.73, 1.15, and 1.70 ยตm. The hydrogels were synthesized by polymerization of 3.6 M N-isopropylacrylamide (N-IPAAm or NIPAM) and
