Abstract

Inthis study, the hydrogels have been synthesized by the crosslinking reactions maleicanhydride-styrene-methyl methacrylate terpolymer with N, N'-methylene-bis-acrylamide and glutaraldehyde in variouscrosslinker ratios. Crosslinking reactions were carried out in the presence of tetrahydrofuranas solvent at 25-50ºC for different time period, and the resulting materialproperties compared. The best conditions for effective crosslinking, i.e., crosslinkingtemperature, time and crosslinker ratios were determined for each crosslinkertype. The swelling behaviour of the hydrogels was examined in Tris-buffersolutions at various pH at 37ºC. Swelling depending on pH was observed in thehydrogels. The pH-dependent swelling of hydrogels was strongly influenced bythe functional group of crosslinker. The molecular structure of the hydrogelswas studied by Fourier Transform Infrared Spectroscopy and their pore structurewas investigated by using Scanning Electron Microscope.

Özet

Bu çalışmada; hidrojeller, maleikanhidrit-stiren-metilmetakrilat terpolimerinin N, N'metilenbisakrilamid ve glutaraldehitin farklı oranları ile çapraz bağlanmasıyla sentezlenmiştir. Çapraz bağlanma reaksiyonları çözücü olarak tetrahidrofuran varlığında farklı zaman periyodunda 25-50ºC aralığında gerçekleştirilmiş ve malzeme özellikleri kıyaslanmıştır. Her bir çapraz bağlayıcı tipi için çapraz bağlanma sıcaklığı, zamanı ve çapraz bağlayıcı oranı gibi etkin çapraz-bağlanma koşulları belirlenmiştir. Hidrojellerin şişme davranışı Tris tampon ortamlarda farklı pH aralığında 37ºC’de incelenmiştir. Hidrojellerin pH-duyarlı olduğu ve pH’ya bağlı şişmenin çapraz bağlayıcının fonksiyonel grubundan etkilendiği görülmüştür. Hidrojellerin moleküler yapısı Fourier Transform Infrared Spektroskopisi ile, gözenekyapısı da taramalı electron mikroskobu ile incelenmiştir.
