Thierry Florent Edme Materne - Richfield OH Francois Kayser - Bertrange, LU Michael Paul Mallamaci - North Canton OH Harlan Roy Wilk - Tallmadge OH
Assignee:
The Goodyear Tire Rubber Company - Akron OH
International Classification:
C08L 4700
US Classification:
524571, 528284, 525342, 525343, 524492, 1522091
Abstract:
The invention relates to the preparation of a silica reinforced rubber composition where alkoxysilane and/or sulfur cure reactions within the elastomer host are controlled by the use of a selected amino acid, or amino acid-containing protein based, activator. The invention also relates to such composite and to a tire having at least one component of such composite.
