摘　　要：介绍了不饱和聚酯封端反应的原理、配方及工艺操作。其中包括丁醇、环己醇、双环戊二烯等一元醇,松香酸、酸酐等一元酸的封端反应。通过封端反应可改进不饱和聚酯的耐腐蚀性、气干性、电绝缘性和与苯乙烯的混溶性等性能。The principle, formula and process operation of blocking reaction for unsaturated polyester were introduced. The blocking reaction using monobasicc alcohol such as butanol, cyclohaxanol and dicyclopentadiene and monoacid such as rosin acid and anhydride as blocking adent were included. The corrosion resistance, air- drying, electric insulation and miscibility of styrene and UPR could be improved by the blocking reaction
