A bio-electrode composition contains (A) a silicone bonded to an ionic polymer and having a structure containing a T unit shown by the following general formula (T1): (R.sup.0SiO.sub.3/2) (T1), the structure excluding a cage-like structure. In the formula, R.sup.0 represents a linking group to the ionic polymer. The ionic polymer is a polymer containing a repeating unit having a structure selected from the group consisting of salts of ammonium, lithium, sodium, potassium, and silver formed with any of fluorosulfonic acid, fluorosulfonimide, and N-carbonyl-fluorosulfonamide. Thus, the present invention provides a bio-electrode composition capable of forming a living body contact layer for a bio-electrode which is excellent in electric conductivity, biocompatibility, stretchability, and adhesion, soft, light-weight, and manufacturable at low cost, and which prevents significant reduction in the electric conductivity even when wetted with water or dried.

This invention relates to a process for forming an azide-grafted polymer. The process comprises mixing a free-radical-reactive polymer with a free-radical initiator and an azide monomer that contains at least one unsaturated C═C bond capable of reacting with a radical, under solid-state grafting conditions, to form an azide-grafted polymer. The formed azide-grafted polymer can be used to prepare a long-chain branched or cross-linked polymer.
