摘要：

A novel soybean oil monoglyceride based unsaturated polyester resin (SOMGUPR) was prepared using two step polymerization with soybean oil,glycerol,1.2-propanediol,maleric anhydride and phthalic anhydride. FT-IR spectroscopy,Gel Permeation Chromatography (GPC) and H-1-NMR spectroscopy were employed to study the chemical structure and molecular weight of this unsaturated polyester resin. The results show that 190 degrees C is the optimal temperature to controll the extent of estification reaction. The number-average molecular weight(Mn) decrease with the increasing value of n(glycerol):n(soybean) oil in SMOGUPR.Also,the side reaction between SOMG and maleric anhydride has not occured as evidenced by H-1-NMR spectroscopy.
