BROMINATED PENTAERYTHRITOLIC POLYESTERS AND PROCESS THEREFOR |
| 摘要 |
<p>Polyesters are prepared by reacting pentaerythritol in the liquid phase with HBr and a dicarboxylic acid having at least four carbon atoms. Bromine replaces some of the hydroxyls in the pentaerythritol while controlled polymerization occurs between the pentaerythritol and the dicarboxylic acid.</p> |
