| Abstract: | The present work deals with the composite of bentonite/polyacrylic acid, a superior water absorbent. The composite was synthesized by adopting the method of polymerization in aqueous solution at high temperature and at high speed. Moreover, the authors inquire into the effects of various factors on the water absorbency of this composite. These factors include amount of crosslinking agent, amount of ultrafine bentonite powder. Surface crosslinking modification of the composite has also been used to improve its water absorbency both in amount and speed, as indicated by the results. |
