摘　　要：坡缕石由于比表面积大,易团聚,并且表面富含极性羟基,故它与非极性有机高聚物的亲和性很差,对其进行有机化改性有着重要的意义。本研究通过微波法合成了有机坡缕石,与常规法比较,微波法能够加快离子的交换速率,并且具有反应时间短、操作工艺简单等特点。Palygorske is possessed of bad affinity with organic polymer because it has high specific surface area, easy agglomeration and a lot of polar hydroxyl groups. Therefore, there have important meanings to organic modification of palygorskite. In this paper, the organic palygorskite was synthesized by microwave method. Comparing with the traditional method, microwave irradiation has the characteristics not only in increasing the speed of ion exchange, predigesting process but also in shortening the reaction time apparently.
