US Patent:

20130116360, May 9, 2013
Filed:

Oct 19, 2012
Appl. No.:

13/656116
Inventors:

BRIDGESTONE CORPORATION - Tokyo, JP
CHRISTOPHER ROBERTSON - Akron OH, US
MARIA UHALL - Uniontown OH, US
Assignee:

BRIDGESTONE CORPORATION - Tokyo
International Classification:

C08J 3/22
US Classification:

523351
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.

US Patent:

20130030133, Jan 31, 2013
Filed:

Nov 24, 2010
Appl. No.:

13/511809
Inventors:

Terrence E. Hogan - Uniontown OH, US
Maria E. Uhall - Uniontown OH, US
William L. Hergenrother - Akron OH, US
Kenji Nakatani - Copley OH, US
International Classification:

C08F 236/10
C08F 2/38
US Classification:

526 82, 526204, 526340
Abstract:

A process for producing functional polymer, the process comprising the steps of reacting an anionic initiator including a functional group with a stabilizing monomer to produce a stabilized initiator, reacting the stabilized initiator with monomer capable of being anionically polymerized to produce a polymer, and terminating the polymer.
