XRD patterns of the samples: a) R2OSn, b) R3OSn, c) R4OSn, d) R5OSn, e) SnO2. An innovative thermal stabilizer for polyvinyl chloride, the micro-nano powders of alkoxyl tin (RxOSn) were synthesized via a solid phase reaction at room temperature, using the surfactant sodium benzene sulfonate (SBS) as a catalyst. The activation energy(Ea) of PVC degradation is closely related to the relative value of exposed crystal surfaces (D(110)/D(101)) and the parity of the alcohol-alkyl chains.
