Abstract Intermolecular metathetic polymer degradation opens up an analytic method to identify the quality and quantity of the components in blends of different types of rubber even if they are crosslinked and filled with carbon black, mineral oil, etc.. Furthermore the amount of soluble and insoluble additives can be determined. Moreover, metathetic degradation allows for determination of detailed information about the chemical microstructure (e.g. sequence length distribution of 1,2-butadiene and styrene units) of the rubbers used. This method is suitable for analysis of rubber components in tires.
