The invention relates to a rubber composition comprising fatty acid modified amines as well as to a method for the treatment of rubbers with fatty acid modified amines. As fatty acid modified amine an amine is chosen that mainly contains primary and tertiary amino groups, with at least one tertiary amino group being present and the fatty acid modification being present on at least one primary amino group. Preferably, as amine a dendritically branched polyalkylene imine is chosen from the group consisting of: 4-cascade:1,4-diaminobutane[4]:propylamine and 8-cascade:1,4-diaminobutane[4]:(1-azabutyliedene)<4>:propylamine. The rubber composition according to the invention has an excellent curing behavior and shows an excellent dispersion of silica-based mineral fillers. The rubber composition according to the invention also has an excellent hardness, tensile strength, elongation at break, tear resistance strength and compressibility. |
