Abstract
Improvements introduced in the preparation of synthetic rubber compositions characterized in that they comprise a substantially saturated elastomer that encloses as a reinforcing agent a furnace carbon black having the following surface characteristics and properties: a volatile content of around from 3 to 8%; a pH comprised between about 1.5 and 4.0; an absorption of diphenyl guanidine of about 25 to 90% for a sample of 0.5 grams; an acid number of less than about 14, the whole of volatile materials being combined with black by a treatment at a temperature below about 232º C by means of a chemical oxidation agent that is more active than molecular oxygen.
