| titleOfInvention |
Elastomer blends having improved extrusion resistance and method for the preparation thereof |
| abstract |
Curable elastomer compositions having improved extrusion resistance comprise from about 50 to 90 parts by weight of a homogeneous blend of rubber, selected from the group consisting of natural and synthetic rubbers and blends thereof, and from about 10 to 50 parts by weight of a block copolymer containing elastomeric blocks and crystalline blocks. The elastomer compositions of the present invention have particular utility as oil well packers. A method for improving the extrusion resistance of curable elastomer compositions comprises the steps of blending together an elastomer, selected from the group consisting of natural and synthetic rubbers and blends thereof with a block copolymer containing elastomeric blocks and crystalline blocks to form a mixture and then curing the mixture. |
