Thermal degradation of deproteinized natural rubber
Thermal degradation of deproteinized natural rubber (DPNR) was investigated by heating at 70 °C and 150 °C for 24 h, which was compared with thermal oxidative degradation of natural rubber (NR). The DPNR was prepared by incubation of the NR latex with urea and sodium dodecyl sulfate at room temperature for an hour followed by centrifugation.

Degradation of non-vulcanized natural rubber - renewable
The oxidative depolymerization of the epoxidized rubber without loss of epoxy groups was fulfilled with (NH 4) 2 S 2 O 8 in the presence of propanal. The resulting epoxidized liquid natural rubber with molar mass around 10 4 was found to have well-defined terminal groups: aldehyde groups and α-β unsaturated carbonyl groups. The degree of epoxidation in degradation products varied from 3.9 to 38 %.

Thermal degradation of epoxidized natural rubber
The effect of neodymium stearate (NdSt) synthesized by saponification method on thermal degradation and thermo-oxidative degradation of expoxidized natural rubber with 25 mol.% epoxidation (ENR25) was investigated by thermogravimetric analysis (TGA), and the structure of ENR25 vulcanized with NdSt after thermo-oxidative decomposition was characterized using Fourier transform infared spectroscopy-attenuated total-reflectance (FTIR-ATR).
