Title
(EN) PROCESS FOR PRODUCING TYRES, TYRES THUS OBTAINED AND ELASTOMERIC COMPOSITIONS USED THEREIN
(FR) PROCEDE DE FABRICATION DE PNEUMATIQUES, PNEUMATIQUES OBTENUS SELON CE PROCEDE ET COMPOSITIONS ELASTOMERES UTILISEES
Abstract
(EN) Process for producing tyres, wherein crosslinking is carried out on a composition comprising: (a) an elastomeric polymer containing carboxylic groups, and (b) an epoxidized liquid organic compound containing epoxide groups located internally on the molecule. Upon heating, the elastomeric material reaches a high degree of crosslinking without the addition of conventional crosslinking agents, with crosslinking times maintained within limits which are acceptable for an industrial use. These compositions are particularly suitable for producing tread bands.
(FR) L'invention concerne un procédé de fabrication de pneumatiques, dans lequel la réticulation est effectuée sur une composition constituée de: (a) un polymère élastomère contenant des groupes carboxyliques, et (b) un composé organique liquide époxydé contenant des groupes époxydes se trouvant à l'intérieur de la molécule. Quand on la chauffe, la matière élastomère atteint un degré élevé de réticulation sans addition d'agents de réticulation conventionnels, avec des temps de réticulation maintenus dans les limites acceptables pour un usage industriel. Ces compositions conviennent particulièrement à la fabrication de bandes de roulement.
