Synthesis and polymerization of a glycidyl methacrylate modified Chitosan

Light-curable polymers can undergo photopolymerization upon light exposure, which shows many advantages compared with chemical polymerization, including a highpolymerization rate that overcomes the solvent effects in normal polymerization, good temporal and spatial control andresolution, ambient temperature operation and low energy consumption. Light-curable polymers may be used for in situ scaffold forming, which makes minimally invasive surgerypossible. Moreover, the light-curable materials may be used for computer-aided fabrication through rapid prototyping which allows fabricating scaffolds with customized shape and reproducible microarchitecture on a large scale. Chitosan is a natural biopolymer that has been widely used in medical applications because of its biocompatibility and biodegradability [1-2]. The purpose of this study was toestablish a new method for the synthesis of photocurable chitosan
