Abstract
The present invention relates to sulfur-vulcanizable silica-containing rubber compounds with improved processability and a process for their production.
Claims15
A rubber compound with improved processability comprising
- a) at least one rubber polymer,
- b) a silane-containing butadiene, a silane containing polyisoprene oil, or a mixture thereof,
- c) a sulfur donor having a melting point <100° C.,
- d) 5 to 120 parts of a silica,
- e) 0 to 100 parts of a rubber carbon black, relative in each case to 100 parts of the rubber polymer.
