| titleOfInvention | Production method of polyester polyol |
| abstract | The invention discloses a production method of polyester polyol. According to the method, natural oil is modified by maleic anhydride and then reacts with small-molecule polyol, dicarboxylic acid or carboxylic ester to obtain a polyester polyol product with high cyclopentane solubility. According to the invention, the modified oil can be led into a polyester body relatively completely so as to improve the functionality of the whole product; the cost of the adopted raw materials is low, and the technology is easy to operate; and particularly in the process of producing low-density polyurethane foam, the solubility of the adopted cyclopentane in polyester polyol can be improved at least to 25%. |
