| Abstract: | The transesterification has been studied by diphenyl methane dicarbamic acid ester with polyester polyol.The influence of catalyst,temperature and time on the reaction were described, the hydroxy-terminated polyurethane lowpolymer was synthesized which molecular weight up to 21,500,the lowpolymer was used into e- poxy resin potting. It has a good toughening effect. |
