Patent ID: 7152642

Claim:
A crosslinked elastomeric product, comprising: at least one first component; and at least one second component; wherein the at least one first component comprises a first elastomeric material crosslinked in substantial absence of sulfur, wherein the at least one second component comprises a second elastomeric material crosslinked with sulfur, wherein the at least one first component is in contact with the at least one second component, wherein the first elastomeric material comprises an elastomeric polymer comprising carboxylic groups, wherein the first elastomeric material is crosslinked by reacting the elastomeric polymer comprising carboxylic groups with an epoxidized liquid organic compound, wherein the epoxidized liquid organic compound comprises epoxide groups located internally along a molecule of the epoxidized liquid organic compound, and wherein the second elastomeric material comprises at least one elastomeric polymer functionalized with at least one epoxide group, at least one carboxylic group, or at least one epoxide group and at least one carboxylic group.
