Abstract
A process for the production of a vulcanized elastomer composition, said process consisting in producing an aqueous dispersion containing at least latex with a small particle size and a filler having undergone a mechanical working stage and conventional vulcanization ingredients, in drying said dispersion and then vulcanizing it in a mould under pressure without subjecting said dried aqueous dispersion to mechanical working.
