Chemoenzymatic synthesis of biodegradable polymers containing glucobiose branches

Polymerizable sugar esters including glucobiose were synthesized from maltose or trehalose and divinyl adipate using enzyme in DMF. ¹³C NMR data showed that 6'-position of maltose and mono-6-position of trehalose were esterified. Further, these glucobiose esters was polymerized with azo-initiator to give the corresponding polymers.
