SUPPORTED MEMBRANES BY THERMAL AND UV INITITATED MASS POLYMERIZATION

Abstract: embodiments in accordance with the present invention encompass a composition comprising one or more of polycyclic olefinic monomers of formula (i) and one or more monomers of formula (iii) for forming anion exchange membrane optionally in combination with one or more monomers of formula (ii). the composition undergoes mass vinyl addition polymerization either under thermal or photolytic conditions and can be formed into ionomers on a suitable membrane support. the membrane supports thus formed are suitable as anion exchange membranes for fabricating a variety of electrochemical devices, among others. more specifically, the ionomeric membranes are formed on a variety of supports which contains a variety of quaternized amino functionalized norbornene monomeric units which are lightly crosslinked (less than five mol %). the membranes so formed exhibit very high ionic conductivity of up to 280 ms/cm at 80� c. the electrochemical devices made in accordance of this invention are useful as fuel cells, gas separators, and the like.
