Abstract
This invention describes chemical modifications of hydrogenated polymers, particularly thermoplastic elastomers, e.g., Kraton.RTM. G, to increase the chemical resistance thereof. The number of residual reactive unsaturated diene-based mid-blocks were reduced through a post-hydrogenation reaction with an alkyl phenyl ether, e.g., anisole. The anisolated thermoplastic elastomer was then further reacted with benzenesulfonylation and nitration reactions to produce even more useful derivatives thereof.
