本文研究偶联剂KH-570对蒙脱土的偶联作用，得到偶联后的产物Mt-k，在水溶液中， 以聚乙烯醇作分散剂、苯乙烯作单体、过氧化苯甲酰作引发剂、利用悬浮聚合接枝的方法，把苯乙烯引发接枝聚合到Mt-k的表面，制得接枝率为23％的苯乙烯接枝蒙脱土产物Mt-k-g-St；研究偶联剂与蒙脱土的偶联情况、和反应条件对苯乙烯接枝蒙脱土的接枝率的影响，并用IR和DSC对接枝产物加以表征。
本文研究偶聯劑KH-570對矇脫土的偶聯作用，得到偶聯後的產物Mt-k，在水溶液中， 以聚乙烯醇作分散劑、苯乙烯作單體、過氧化苯甲酰作引髮劑、利用懸浮聚閤接枝的方法，把苯乙烯引髮接枝聚閤到Mt-k的錶麵，製得接枝率為23％的苯乙烯接枝矇脫土產物Mt-k-g-St；研究偶聯劑與矇脫土的偶聯情況、和反應條件對苯乙烯接枝矇脫土的接枝率的影響，併用IR和DSC對接枝產物加以錶徵。

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．
