ABSTRACT:
The present invention relates to novel chromatography stationary phases comprising non-polysaccharide carbohydrate polyethers and methods for their preparation. Particularly, the invention relates to chromatography stationary phases comprising said carbohydrate polyethers and more particularly to chiral stationary phases. Also, since the carbohydrate polyethers of the present invention can be conveniently prepared with controlled functionality, molecular weights and polydispersity indices as well as controlled microstructure, tertiary structure stationary phases prepared from these polymers can be conveniently modified or custom synthesized to accommodate specific separation requirements.
