TI  - Epoxide groups in natural rubber. 1. 13C-NMR study of oxidative degraded rubbers
PY  - 1998///
PB  - Journal of Rubber Research
N2  - Epoxide groups in natural rubber, which are derived from oxidative degradation of the polymer, are found to be mainly in cis configuration. The amount of trans epoxide, on the other hand, increases with increasing degradation temperature of the natural rubber. The presence of cis epoxide groups in low molecular weight fractions of natural rubber, therefore, may be associated to by-products of oxidative degradation of the polymer
