Polydienes possessing terminal ionic groups part 1 preparation of polydienes with terminal quaternary ammonium groups

This is the authors' abstract. We don't add key points for this paper.

Methods are described by which living anionic polydienes are reacted with α, ω‐alkylene‐chloroamines to generate polymers possessing terminal tertiary amine groups. Subsequent reaction with alkyl halides yields materials with quaternary ammonium terminal ligands. Evidence is presented to show that both reaction steps proceed with high efficiency, so that overall conversion is virtually quantitative. The ionically terminated polydienes exhibit two phase morphology, and the difunctional materials have thermoplastic elastomeric properties.
