| Abstract: | The acetone was replaced with dimethyl formamide in the synthetizing of waterborne polyurethane.The chain extending reaction slowed down by using phosphoric acid and the quantities of solvent were reduced greatly in the synthetic reaction.So the solvent needn't be removed. As a result, the production cost and the process were reduced and simplified, separately. |
