Abstract
Commercial highly cis-1,4-polybutadiene was cured out by benzoyl peroxide from 3 to 12 phr in toluene solution. The structural characterization of resulting gel fraction or cured rubber was carried out in both swollen- and solid-state 13C-NMR measurements. The assignment of observed chemical shift proposed by using a shift factor method and empirical calculation using HOSE method.
