An easy way to sugar-containing polymer vesicles or glycosomes.

A thioglucose derivative was effectively grafted onto the double bonds of a 1,2-polybutadiene-block-polystyrene through photoaddition at room temperature. A so prepared amphiphilic glycopolymer (17 wt % glucose) could be dispersed in organic and in aqueous media, leading to the formation of sugar-containing polymer vesicles or "glycosomes".
