A series of biodegradable and hydroxylated polyester was synthesized by acid-induced epoxide ringopening polymerization with fumaric acid,1,3-butadiene diepoxide and terephthalic acid as materials.The structures of the polymer were characterized by1 H-NMR,Fourier transform infared spectroscopy(FTIR)and gel permeation chromatography(GPC).Thermal properties were tested by thermal gravity analysis(TGA)and differential scanning calorimetry analysis(DSC).Hydrophilicity was detected by air-water contact angle mea...
