摘要：The internally plasticized PVC materials by displacement of chlorine with mannich base of cardanol butyl ether, that is, the covalent attachment of the cardanol-based internal plasticizer to the PVC matrix, is descried for the first time. The chemical structure and properties of cardanol-based internal plasticizer and internally plasticized PVC materials was characterized. The results showed that the T-g of self-plasticization PVC material decreased from 85.6 to 49.3 degrees C when chlorine atoms in PVC were substituted with mannich base of cardanol butyl ether, tensile strength decreased from 30.33 to 18.86 MPa, and the elongation at break increased from 180.37% to 357.20%, which illustrated that mannich base of cardanol butyl ether played internally plasticized effect on PVC. The internal plasticization mechanism was also studied. Self-plasticization PVC films showed no migration in n-hexane, but 15.7% of DOP leached from the DOP/PVC system into n-hexane. The PVC materials were expected to be commercial application in producing food packing, toys, and medical devices with high requirements in migration resistance.
