Patent
CA 2364587
The invention relates to rubber compounds that contain rubbers polymerized in solution with a secondary hydroxyl group content of 0.1 to 5 wt.- % that are not more than 4 carbon atoms away from the respective side chain end. The invention also relates to mixtures thereof with fillers, optionally additional rubbers and rubber auxiliary agents and the vulcanized rubbers produced thereof. The inventive rubber compounds are useful for producing highly reinforced, abrasion-resistant molded bodies, especially for producing tires that are characterized by excellent non-skid properties on wet surfaces.
L'invention concerne des mélanges de caoutchouc contenant des caoutchoucs polymérisés en solution comprenant entre 0,1 et 5 % en poids de groupes hydroxyle secondaires qui ne se situent pas au-delà de 4 atomes de carbone de chaque extrémité de chaîne latérale. L'invention concerne en outre leurs mélanges contenant des charges, éventuellement d'autres caoutchoucs et auxiliaires appropriés, ainsi que des produits de vulcanisation obtenus à l'aide desdits mélanges. Ces mélanges de caoutchouc s'utilisent pour produire des corps moulés très renforcés résistants à l'usure, notamment pour produire des pneus présentant des propriétés antidérapantes sur chaussée mouillée particulièrement marquées.
