In this study, new hydrogels in rod shape were prepared from N-isopropyl acrylamide (NIPA), N-acryloyltris-(
hydroxymethyl) aminomethane (NAT) and N,N0-methylenebisacrylamide (BIS). The effect of the
incorporation of NAT into poly(N-isopropyl acrylamide) (PNIPA) structures for which the monomer composition
was varied from NIPA 100% to NAT 100% was explored. The rheological studies were used to test
their viscoelastic properties. Swelling experiments were used to test the capacity of water absorption, the
modification of the network parameters, the swelling kinetics, the temperature and pH swelling response
and
