Abstract
The present invention is generally directed to a process for forming a diene-rubber grafted centipede polymer. The process includes copolymerizing a copolymer comprising a maleimide and at least one block chosen from the group consisting of vinyl aromatic hydrocarbons, R R ethylenes, or alkyl vinyl ethers with an amine. The amine is further functionalized with at least one functional group capable of grafting to a diene rubber. The copolymer is cocured with a diene rubber to form the diene-rubber grafted centipede polymer.
