✦ Synopsis

To develop a new synthetic polymer containing sugar branches, radical polymerization of the reducing vinyl sugar ester 6-O-vinyladipoyl-~-glucose (1) was performed in an organic solvent or in water. The polymers obtained with several azoinitiators in dimethylformamide (DMF) showed comparatively low average molecular weight (an = 4500). In contrast, the use of a redox initiator (FeS04 and H202) in water gave polymers of higher average molecular weight (a, = 33000) in higher yield (90%), followed by crosslinking at high conversions.
