| description | The invention discloses hydroxyl-containing polyester and a preparation method thereof. The preparation method provided by the invention is completely different from the previous synthesis method. A hydroxyl-containing dicarboxylic acid compound and a dibromo compound are used as initial raw materials, dimethyl sulfoxide and N,N-dimethylformamide are used as solvents, tetramethylguanidine is added as a catalyst, and the disclosed compound is prepared by a one-pot method at room temperature. The hydroxyl-containing dicarboxylic acid compound is any one of tartaric acid and malic acid; and the dibromo compound is any one of 1,2-dibromoethane, 1,3-dibromopropane, 1,4-dibromobutane, 1,5-dibromopentane, 1,6-dibromohexane and 1,8-dibromooctane. The method has the advantages of simple operation, normal temperature reaction and easily available raw materials.
本发明公开了一种含羟基聚酯及其制备方法。本发明的制备方法完全不同与之前的合成方法，本发明以含羟基二羧酸化合物、二溴化合物为起始原料，以二甲基亚砜、N，N-二甲基甲酰胺位溶剂，同时加入四甲基胍作为催化剂，在常温下一锅法制备而成；其中含羟基二羧酸化合物为酒石酸、苹果酸中的任意一种；二溴化合物为1，2二溴乙烷、1，3二溴丙烷 |
