FIELD: chemistry.
SUBSTANCE: invention relates to a vulcanizable elastomer composition comprising a secondary accelerator, a vulcanization method, and to a tire comprising the composition. Vulcanizable elastomer composition includes a diene elastomer, a reinforcing filler, a sulfur-containing vulcanization system and a compound of formula (I).
EFFECT: invention eliminates guanidine or derivatives thereof by introducing a compound of formula (I) as a secondary accelerator, accelerates the elastomeric composition vulcanization process, reduces the Payne effect and reduces the migration of the accelerator from the composition.
