This article is concerned with the microstructural changes during peroxide and high pressure vulcanization of polybutadiene that is unfilled and filled with carbon black. The main tool is 13 C solid-state NMR; it shows that vinyl unsaturations are consumed in both filled and unfilled samples under p
