dc.description.abstractIn this work, novel hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and different poly(alkylene glycol)(meth)acrylates (BIS) were prepared by radiation-induced copolymerization. The influence of different BIS types with variation in chain length, based on ethylene glycol (EG) and/or propylene glycol (PG) pendant units, on the nature and inherent properties of P(HEMA/BIS) copolymeric hydrogels was the main idea of this paper. Swelling studies were conducted for all types of P(HEMA/BIS) copolymeric hydrogels in a wide pH and temperature range. Additional characterization of structure, morphology and thermal behaviour of the obtained hydrogels was conducted by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and thermogravimetric (TG) analysis. The modelling of drug release and diffusion characteristics was tested using cephalexin (CEX). The results indicate that P(HEMA/BIS) hydrogels properties are significantly dependent on the type of BIS. The hydrogels with ethylene glycol (EG) pendant chains show a noticeable pH and/or temperature sensitivity and can be considered smart hydrogels. The introduction of propylene glycol (PG) units, pure and mixed with ethylene glycol (EG) pendant chains, can additionally tune the characteristics of such gels. Furthermore, drug release studies indicate that these types of P(HEMA/BIS) copolymeric hydrogels are suitable candidates for controlled drug release systems. (C) 2010 Elsevier B.V.
