| Abstract: | This paper is a study of the coupling effect of coupling agent KH-570 on montmorillonite，which involves producing Mt-k．With polyvinyl alcohol as dispersing agent，styrene as monomer and benzoyl peroxide as initiator in the water solution，Mt-k-g-st，grafted matter of styrene and montmorillonite，could be made by means of suspended grafting，in which styrene is initiated and grafted onto the surface of Mt-k．Our study focuses on the coupling conditions of coupling agent with montmorillonite and the effect of reacting condition on the grafting ratio of styrene grafting montmorillonite．Besides，the grafted matter is further verified with IR and DSC． |
