23221-4169 ABSTRACT Rubber mixtures which can be easily processed and have good mechanical properties and are based on synthetic and/or natur- al grades of rubber, the usual additives also being used, contain a copolymer with a melt viscosity of not more than 150 Pa.s., meas- ured at 180°C, of a) 4 to 95% by weight of at least one alkyl ester of .alpha.,.beta.- ethylenically unsaturated mono- and/or di-carboxylic acids which contains 1 to 12 carbon atoms in the alcohol radical, b) 0.5 to 15% by weight of at least one amide of .alpha.,.beta.-ethy- lenically unsaturated mono- and/or di-carboxylic acids, c) 0.2 to 10% by weight of at least one .alpha.,.beta.-ethylenically unsaturated mono- and/or di-carboxylic acid and d) 0 to 50% by weight of at least one other .alpha.,.beta.-ethylenically unsaturated copolymerizable monomeric compound, the sum of the percentages in each case being 100. Rubber articles and motor vehicle tyres with very good mechanical properties can be produced from these rubber mixtures.
