After that, obtained alcoholysis products reacted with maleic anhydride and phthalic anhydride ，and then the styrene was added in order to dilute the resin and became cross-linking. Finally，we obtained the unsaturated polyester resin. The synthesis process and optimum formula is simple, cheap, environmental friendly and economical, etc. The final product is stable and has a good intensity. Key words: mixed alcohols; unsaturated polyester resin; PET; poly(ethylene terephthalate) 学法。物理法相对比较简单，主要是通
