摘要：

The chemical structure of polybutadiene thermally crosslinked at temperatures up to 250-degrees-C was characterized by high resolution solid state C-13 n.m.r. spectra in combination with high resolution H-1 and C-13 magic angle spinning n.m.r. spectra of the swollen gel. Crosslinking is shown to involve the reaction of a vinyl group with the methylene group in 1,4-cis/1,2 sequences.
