摘要

A novel polymer containing the sucrose group was synthesized by radical polymerization from an enzymaticallyprepared monomer

l'-O-vinyledipoyl-sucrose (VAS). Transesterification reaction of sucrose with divinyl adipate inanhydrous pyridine catalyzed by an alkaline protease from Bacillus subtilis at 60℃ for 7 days gave VAS (yield 55%) withoutany blocking/deblocking steps. The vinyl sucrose ester could be polymerized with potassium persulfate and H2O2 as initiatorto give poly(l'-O-vinyladipoyl-sucrose)with Mn=33

000 and Mw=53

200

Mw/Mn=1.61.The polymer was biodegradable.After 6 days in aqueous buffer (pH 7)

this alkaline protease could degrade poly(1′-O-vinyladipoyl-sucrose) to Mn of ca. 1080

Mw/Mn=3.30(37℃)

and Mn of ca.5200

Mw/Mn=2.44(4℃).The polymer containing the sucrose branch would be a functional material in various application fields.
