| Abstract: | Polymers composed of silyl ester bonds in the main chain were investigated as a new class of degradable polymers. This paper first reported the synthesis and properties of degradable poly (silyl ester) s by 1,1,3,3-tetramethyldi-acetoxydisiloxanes with adipic acid.. The chemical structures of the polymer was confirmed by 1H-NMR. The properties of the poly(silyl ester)s was researched by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA)and gel permeation chromatography(GPC). |
