| Abstract: | Water swelling rubber was prepared by natural rubber latex grafted with acryl amide by oxidation-reduction system (K2S2O8/Na2S2O3) under the ordinary condition. The effects of the reaction temperature, time, and the amount of the initiator on grafting reaction were studied. The grafting efficiency and grafting rate were measured by using the Soxhelt extraction method, and the effects of the amount of the acryl amide and N, N'-Methylene-bis-(acrylamide) on the water swelling capacity were determined. |
