-g(a),-g(b),-g(b)-TRIFLUOROSTYRENE-BASED AND SUBSTITUTED -g(a),-g(b),-g(b)-TRIFLUOROSTYRENE-BASED COMPOSITE MEMBRANES

(57) The composite membrane which 含漬 (ed) the porosity base material with the polymer composite including various combination of the monomer unit which uses Summaries alpha and beta, beta* truffe ルオロ styrene, Substitution alpha and beta, beta* truffe ルオロ styrene, and ethylene as a base is offered. When a polymer composite contains an ionic exchange portion, the composite membrane obtained is useful in an electrochemistry use, and useful as a film electrolyte in an electrochemistry fuel cell especially.
