| Abstract: | Vinyl sugar ester, 6-O-vinyladipoyl-d-glucose (VAG), was polymerized with vinyl fatty acid esters in dimethylformamide (DMF) with azobisisobutyronitrile (AIBN)
to produce new amphiphilic polymers having branches of sugar and fatty acid esters. The influence of structural variations
by changing the length of the alkyl chain of fatty acid moiety was examined by measurements of the surface tension and biodegradability.
