Water uptake in chemically crosslinked poly(acrylamide-co-crotonic acid) hydrogels

Karadag, E; Uzum, OB; Saraydin, D (ELSEVIER SCI LTD, 2005)

The aim of this study was to investigate that swelling capability of acrylamide (AAm) hydrogels by adding hydrophilic co-monomer such as crotonic acid (CA). Superswelling poly(acrylamide/crotonic) acid, poly(AAm-co-CA) ...

Swelling characterization of gamma-radiation induced crosslinked acrylamide/maleic acid hydrogels in urea solutions

Karadag, E; Uzum, OB; Saraydin, D; Guven, O (ELSEVIER SCI LTD, 2006)

Swelling behaviors of crosslinked acrylamide/maleic acid (CAMA) hydrogels synthesized by gamma-radiation crosslinking of acrylamide and maleic acid in aqueous urea solutions were investigated. CAMA hydrogels containing ...

Water absorbency studies of gamma-radiation crosslinked poly(acrylamide-co-2,3-dihydroxybutanedioic acid) hydrogels

Karadag, E; Saraydin, D; Guven, O (ELSEVIER SCIENCE BV, 2004)

Water absorbency behaviour of acrylamide (AAm)/2,3-dihydroxybutanedioic acid (DBA) hydrogels synthesized by, gamma-radiation crosslinking of AAm and DBA in an aqueous solution was investigated. Different amounts of DBA ...

Immobilization of Saccharomyces cerevisiae on to acrylamide-sodium acrylate hydrogels for production of ethyl alcohol

Oztop, HN; Oztop, AY; Karadag, E; Isikver, Y; Saraydin, D (ELSEVIER SCIENCE INC, 2003)

Acrylamide/sodium acrylate (AAm/SA) copolymers, prepared by using various crosslinkers, were used in experiments on swelling, diffusion, immobilization of yeast cells (Saccharomyces cerevisiae) and production of ethyl ...

Binding of some dyes onto crosslinked poly (N-vinylpyrrolidone)

Saraydin, D; Karadag, E (SPRINGER, 2000)

Bindings of some anionic dyes containing sulfonyl group(s), namely, Acid Blue 74 (AB-74), Acid Orange 7 (AO-7), Acid Green I (AG-1), Direct Blue 53 (DB-53), and Calconcarbosylic acid (CCA) onto crosslinked poly(N-vinylpyrrolidone) ...

In vivo biocompatibility of radiation crosslinked acrylamide copolymers

Saraydin, D; Unver-Saraydin, S; Karadag, E; Koptagel, E; Guven, O (ELSEVIER SCIENCE BV, 2004)

In vitro swelling and in vivo biocompatibility of radiation crosslinked acrylamide copolymers such as acrylamide/crotonic acid (AAm/CA) and acrylamide/itaconic acid (AAm/IA) were studied. The swelling kinetics of acrylamide ...

Swelling studies of copolymeric acrylamide/crotonic acid hydrogels as carriers for agricultural uses

Karadag, E; Saraydin, D; Caldiran, Y; Guven, O (JOHN WILEY & SONS LTD, 2000)
