Thermal oxidation resistance of rare earth-containing composite elastomer

摘要

The rare earth-containing composite elastomer was obtained by the reaction of vinyl pyridine-SBR(PS- BR)latex with rare earth alkoxides, and its thermal oxidation resistance was studied. After aging test, it is found That its retention rate of mechanical properties is far higher than that of the control sample. The results of thermo- Gravimetric analysis show that its thermal-decomposing temperature rises largely.
