Abstract
Embodiments of the present disclosure encompass vinyl addition and ROMP polymers having at least one type of repeating unit that encompasses a comprise N+(CH3)3OH− moiety. Other embodiments in accordance with the disclosure include alkali anion-exchange membranes (AAEMs) made from one of such polymers, anion fuel cells (AFCs) that encompass such AAEMs and components of such AFCs, other than the AAEM, that encompass one of such polymers.
Claims6
A vinyl addition norbornene-type polymer consisting essentially of:
- a first type of repeating unit derived from a norbornene-type monomer represented by Formula A:
- where for Formula A, m is from 0 to 3, at least one of R9, R10, R11 and R12 is a quaternary ammonium cation and the others of R9, R10, R11 and R12 are independently a hydrogen, a C1 to C5 alkyl, an aryl or an alkyl-aryl group;
- and
- a second type of repeating unit derived from a norbornene-type monomer represented by Formula B:
- where for Formula B, m is as defined above and at least one of R13, R14, R15 and R16 is selected from a substituted or unsubstituted maleimide-alkyl pendent group, where the alkyl is a C1 to C6 alkyl, or an another cross-linkable group, and the others of R13, R14, R15 and R16 are independently selected from a hydrogen, a C1 to C12 alkyl, an alkyl-aryl or a methyl glycol ether.
