ABSTRACT:
A styrene derivative carrying N-acethylchito-oligosaccharide chains, a polystyrene derivative carrying N-acetylchito-oligosaccharide chains on the side chains as well as a method for preparing these compounds are herein disclosed. The method for preparing the styrene derivative comprises reacting N-acetylchito-oligosaccharide lactone with vinylbenzylamine or a derivative thereof while the method for preparing the polystyrene derivative comprises polymerizing the styrene derivative. These derivatives can be employed as biomedical materials, in particular as materials for cell culture.
