PURPOSE:A functional elastomer suitable as an optical memory element, etc., capable of being made into a film, having high hardness, having a specific structural formula with a main chain into which a viologen unit is introduced, by cationic polymerization using a bifunctional initiator. CONSTITUTION:A functional elastomer shown by the formula (X is polyether) and 2A<->(A is anion) or A<2->, having a main chain into which a viologen unit is introduced, by cationic polymerization using a bifunctional initiator (preferably acid anhydride such as trifluoromethanesulfonic acid anhyride, etc., or dicarbonium salt such as styrene dimer dicationic salt, etc.).
