摘要： A vulcanizable rubber composition is provided that comprises an elastomer, a reinforcing filler comprising silica or a mixture thereof with carbon black, a silica dispersing aid comprising about 0.1 to about 15 phr poly(vinyl acetate) (PVA), and a cure agent. The addition of PVA to the composition improves the processability of the compound, improves the tear strength and modulus of the rubber and can reduce the number of mixing stages during compounding, resulting in lowering of the cost of operation and increasing plant productivity without compromising the processability or other physical properties of the stocks. Also provided are a vulcanizate formed from vulcanizing the rubber composition, a tire component formed from the vulcanized rubber and a process for forming the tire component.

摘要： A method for controlling any increase in Mooney viscosity during aging of siloxane-functionalized polymers includes the step of adding a viscosity stabilizing effective amount of a long chain alcohol preferably selected from the group consisting of aliphatic, cycloaliphatic, and aromatic alcohols having more carbon atoms than the hydrolyzable substituent on the siloxane end groups. The method provides for the stabilization of Mooney viscosity of siloxane-functionalized polymers at any given level upon aging. The long chain alcohols react with the siloxane-functionalized polymers prior to hydrolysis of the siloxane end groups to form moisture stabilized polymers.

摘要： The invention provides a sulfur vulcanizable silica-reinforced elastomeric compound having improved tensile mechanical and dynamic viscoelastic properties. The compounds are formed by mixing an elastomer optionally having an alkoxysilane terminal group, with silica in the presence of an alkyl alkoxysilane for desired processability and a mercaptosilane for increasing the bound rubber content. In particular, the mercaptosilane and the alkyl alkoxysilane are present in a ratio of a maximum of 0.14:1. Preferably, the mercaptosilane and the alkyl alkoxysilane are compounded with the elastomer and the silica at high temperature in the first mixing stage.

The method provides for the stabilization of Mooney viscosity of siloxane-functionalized polymers at any given level upon aging. The viscosity stabilizing agents react with the siloxane-functionalized polymers during hydrolysis of the siloxane end groups to form moisture stabilized polymers.
