| Abstract: | The synthesis and properties of new chain extender 4 - hydroxyl- N (2 - h ydroxy e th yl ) -butyramide are introduced,which is used for PU castable elastomer. The results show that the synthesis with solvent-free method is better- The properties of elastomer based on this chain extender are discussed. |
