摘要

1/1 summary “amino or phosphine functionalized block polymers, selectively halogenated block polymers, precursor block, membrane or film, apparatus, electrodeionization assembly, and method for preparing the copolymer Amino or phosphino-functionalized block dimer - Selectively functionalized amino and phosphine block copolymers and their preparation, for use as anion exchange membrane materials. selectively functionalized block copolymers have at least two end blocks each of which are substantially free of amino and phosphino functional groups and have at least one inner block d which on average comprises at least one unit of functionalized polymer in amino and phosphine of the formula (i) wherein z is nitrogen or 12 phosphorus; R is hydrogen or alkyl; r is hydrogen or tertiary alkyl; each independently is hydrogen or alkyl optionally 1 to b substituted with one - (a-nr) r; or two groups r together with the z to which they are attached form an optionally substituted ring; x is 1, 2 1 or 3; straight chain alkylene optionally substituted with one or more b methyl and / or ethyl groups; and r and r each independently is hydrogen or alkyl; or a corresponding anion salt.
