摘要
本文研究了由聚酯改性合成不饱和聚酯树脂的反应机理和工艺条件 ,讨论了改性树脂反应活性与不饱和酸结构之间的关系 ,解释了顺、反式双键结构对改性树脂固化放热特性和反应活性不同的原因。
The preparation conditions of unsaturated polyester (UP) resins modified by PET were introduced in this paper.The copolymerization mechanisms of the synthesis of UP resins from cis-and trans-anhydride were researched.The relationship between the modified resins activities and the structure of unsaturated acids were also discussed.The reason for the differences of the exothermal curves of the two resin systems was that the activity of the cis-and trans-unsaturated bonds was different from each other.
