Abstract
An ionically conductive material comprises crosslinked copolymer prepared by the reaction of (A) organopolysiloxane and polyoxyalkylene copolymer, which has at least 2 silicon-bonded hydrogen atoms in each molecule, with (B) polyoxyalkylene having at least 2 aliphatically unsaturated hydrocarbon groups in each molecule, and (C) metal ion from Group I or Group II of the Periodic Table, wherein said metal ion is dispersed in said crosslinked copolymer. Component (B) is a polyoxyalkylene having an aliphatically unsaturated hydrocarbon group at both chain terminals or a mixture of molecules in which some have an aliphatically unsaturated hydrocarbon group at both ends and some having the group at only one end. This mixture gives the highest conductivity.
