| Abstract: | The grafting of 4-vinylpyredyne and 2-vinylpyredyne onto pre-irradiated F_(46) film was investigated.The conditions of the preparation of anionexchange membranes were studied.Based on the condition obtained,larger weak ionexchange membranes were prepared successfully with the new type of reaction instrument designed by ourselves.The kinetics of the grafting was also studied and the electrical properties and mechanical strength of the film were determined.The strength of the obtained weak alkaline ionexchange membranes,which had a larger size and auniform ionexchanging capacity,were fit for most of the electrolytic reactors. |
