Two different methods for the rapid microwave-assisted amination of halide-functionalized polymers were investigated. Nucleophilic substitution by phthalimide, followed by ring opening with methylamine to liberate the free amine, afforded amino-substituted polymers with up to 76% conversion. The second method involves nucleophilic substitution with azide ions and subsequent treatment with triphenylphosphine. The latter method was found to be more efficient, with up to 99% conversion in favourable cases and with a reaction time of 2 x 30 min.
