中文摘要：

以福建龙岩高岭土为主要原料,用沉降的方法得到平均粒径为1.75μm的沉降高岭土。用DMSO插层高岭土,后用苯乙烯单体取代前驱体中的DMSO分子,产物经四氯化碳洗涤后,在马弗炉中270℃本体聚合2h得到高岭土/聚苯乙烯复合物。红外在1 453,1 499和1 606cm-1的吸收振动峰证明了聚苯乙烯的存在。XRD结果显示高岭土层间距0.712nm,苯乙烯聚合后片状结构已经被剥离。热重显示聚苯乙烯占复合物质量的40%,还有约5%的未除去DMSO和4.8%的羟基,估算出高岭土∶聚苯乙烯=1.375∶1（质量比）。扫描电镜也验证了这种剥离。

英文摘要：

The synergistic stabilization effect of different metal lanolin fatty acids as natural-based thermal stabilizers for poly（vinyl chloride）（PVC） incl u ding calcium lanolin fatty acid（Calan2）,zinc lanolin fatty acid（Znlan2） and L anthanum lanolin fatty acid（Lalan3） were studied.The processability of PVC was tested by torque rheometer,the mechanical properties were studied by universa l testing machine,and the coupling effect of product in PVC/CaCO3 was also re sea rched.The results indicated that the properties of Lan/Zn stabilizer was bette r than Ca/Zn stabilizer and compound lead salt except static stability and dynami c stability.
