摘　　要：叙述了双环戊二烯（ DCPD）改性不饱和聚酯树脂（ UPR）的技术，讨论了投料顺序、原料比、 DCPD纯度、反应温度对产品性能的影响，通过实验发现最大影响因素是DCPD／MA的比，其次是反应温度，投料顺序影响树脂的活性， DCPD纯度对树脂性能基本没有影响。确定了合成最佳工艺条件： AM／PM比应该大于1， DCPD／AM＝0．5～0．6，反应温度为200℃。Synthetic technique of dicyclopentadiene （ DCPD ） and unsaturated polyester resin （ UPR ） were narrated.Influencing factors and product properties of the technological conditions were discussed, including mixing procedure, compare to raw material, purity of DCPD and reaction temperature.The biggest influence factor was DCPD/MA ratio.The second influence factor was the reaction temperature.The mixing procedure affected the activity of resin, and purity of DCPD had no effect.The optimal process was determined by using experiment.AM/PM ratio should be greater than 1 , DCPD/AM=0.5~0.6 , and reaction temperature was 200 ℃.
