The invention discloses a hydroxyl-containing polyester and a preparation method thereof. The preparation method of the present invention is completely different from the previous synthesis method. The present invention uses a hydroxyl-containing dicarboxylic acid compound and a dibromo compound as starting materials, and uses dimethyl sulfoxide, N,N-dimethylformamide as a solvent, At the same time, tetramethylguanidine was added as a catalyst, and it was prepared by a one-pot method at room temperature; wherein the hydroxyl-containing dicarboxylic acid compound was any one of tartaric acid and malic acid; the dibromo compound was 1,2 dibromoethane, 1 , any one in 3-dibromopropane, 1,4-dibromobutane, 1,5-dibromopentane, 1,6-dibromohexane, 1,8-dibromooctane. The advantages of the present invention are: simple operation, normal temperature reaction, and easy-to-obtain raw materials. |
