摘 要：The synergistic stabilization effect of different metal lanolin fatty acids as natural-based thermal stabilizers for poly（vinyl chloride） （PVC） including calcium lanolin fatty acid （Calan2）,zinc lanolin fatty acid （Znlan2） and lanthanum lanolin fatty acid （Lalan3） were studied through Congo red testing,color measurements,FTIR analyses and thermal behavior in this paper. The results showed that Lalan3/Calan2/Znlan2 stabilizers exhibited more excellent thermal stabilization efficiency to PVC than Calan2/Znlan2 thermal stabilizers,and the optimal mass ratio of Lalan3/Calan2/Znlan2 was 8:9:3. At last,the effect of degradation mechanism on PVC and synergistic stabilization was also investigated by FTIR analyses and thermal behavior.
