以聚己内酯多元醇为核合成了支化聚酯，并通过有机硅改性得到了一系列不同有机硅含量的改性产物；并对树脂和白色漆的漆膜性能进行了试验。实验表明，漆膜具有良好的物理机械性能和耐温变性能。
The branched polyester has been synthesized based on polycaprolactone polyols as kernel, and its modified products were prepared with organic silicone. The film performance of the resin and its white paint was tested. The results showed that the coatings have good physical and mechanical properties,especially the low tem-perature flexibility.
