摘要
为了提高国产不饱和聚酯的气干性，选用部分饱和的二元酸酐并添加干性油，合成了适合配制汽车修补腻子（原子灰）用的非蜡型、于空气中可速干的不饱和聚酯。此外，还研究了工艺流程对不饱和聚酯的性能影响，结果表明，不饱和聚酯的合成反应必须在反应开始的回流温度下至少保温１ｈ。
In order to raise air dried property of unsaturated polyester,partly saturated binary acid anhydride and dry oil have beed filled in formulas.The non wax unsaturated polyester which has been composed to prepare the putty for repairing vehicle is fast dried in air.In addition,influence of the technical process on the properties of unsaturated polyester has been researched. As a result,it is necessary to keep one hour at least in the reflowing temperature. [
