Poly(ethylene glycol) methyl ether late and Gelatin
Keyword Poly(ethylene glycol) methyl ether acrylate Interpenetrating Polymer Networks IPN Hydrogel Gelatin Gelatin Hydrogel IPN Interpenetrating Polymer Networks Poly(ethylene glycol) methyl ether acrylate Abstract This article describes the synthesis of interpenetrating polymer networks (IPNs) based on Poly(ethylene glycol) methyl ether acrylate (PEGMEA) and gelatin,which were crosslinked sequentially using N,N’-methylene bisacrylamide (NMBA) and glutaraldehyde, respectively. Various samples were prepared by taking varying amounts of PEGMEA and gelatin in the initial feed. Sequential IPNs were prepared by first polymerizing and crosslinking PEGMEA in the presence of gelatin using redox initiators (Ammonium Peroxydisulfate and N,N,N',N'- tetramethylethylenediamine) and NMBA as a crosslinking agent. Gelatin present in the firm gels was then crosslinked using 1% glutaraldehyde. Characterization of these gels was done by measuring their swelling behavior.
