Abstract

(1) When rubber treated with hydrazine-hydrate after cold-vulcanization was compared with the untreated rubber in the swelling test, it was known that thioketon-type sulfur changes itself to constitute ketoazine crosslinkage.<br>(2) If thioketon groups transform into ketoazine crosslinkage, a certain kind of relation should exist between the contents of thioketon-type sulfur and N-contents. This fact was recognized in natural rubber and cis-i, 4-polybutadiene cold-vulcanizates. Principal reaction is thought as follows: _??_
