A silicone-polyester copolymer has the formula Xg[ZjYo]c, wherein each X is an independently selected silicone moiety having a particular structure, each Y is an independently selected polyester moiety, each Z is an independently selected siloxane moiety, subscript c is from 1 to 150, subscript g is >1, 0<=j<2, and 0<o<2, with the proviso that j+o=2 in each moiety indicated by subscript c. Methods of preparing the silicone-polyester copolymer are also disclosed. Further, a sealant is disclosed, the sealant comprising the silicone-polyester copolymer and a condensation-reaction catalyst. 一种硅酮-聚酯共聚物具有式Xg[ZjYo]c，其中每个X是独立选择的具有特定结构的硅酮部分，每个Y是独立选择的聚酯部分，每个Z是独立选择的硅氧烷部分，下标c为1到150，下标g>1，0≤j<2并且0<o<2，条件是在由下标c指示的每个部分中，j+o＝2。还公开了制备所述硅酮-聚酯共聚物的方法。进一步地，公开了一种密封剂，所述密封剂包括所述硅酮-聚酯共聚物和缩合反应催化剂。
