| 摘要 |
The present invention is directed to a method of increasing the green strength of a rubber composition, comprising the step of combining in the rubber composition, a copolymer comprising: a polymeric backbone chain comprising a diene based elastomer selected from the group consisting of solution polymerized styrene butadiene rubber, emulsion polymerized styrene butadiene rubber, natural polyisoprene rubber, synthetic polyisoprene rubber, and polybutadiene; and polymeric sidechains bonded to the backbone chain, the sidechains comprising a polymer derived from an N-substituted monoalkyl acrylamide. |
