Preparation and Application of Organic Thermal Stabilizer VAS for PVC
Vanillin-Aniline Schiff' s base(VAS) was synthesized.Function and the influence of VAS doped with CaSt2,ZnSt2 and LDH stearate system for polyvinyl chloride (PVC) were also studied.The results showed that the synergy of ZnSt2 and VAS was better than the synergy of CaSt2 and VAS,that VAS doped with ZnSt2 and LDH stearate system could effectively improve the thermal stability of PVC,of which the best ratio of VAS/ZnSt2/LDH composite heat stabilizer system was 5/3/2.
