Abstract
The present disclosure is directed to methods for preparing rubber compositions where those rubber compositions comprise at least one telechelic polymer and at least one filler. The methods make use of a mixer that includes a mixing chamber and at least one rotor with wings of specified configuration. Use of the disclosed methods yields a rubber composition with improved properties including an improved dispersion index after master batch mixing as compared to the same rubber composition mixed using standard 4 wing mixers.
