1. THE METHOD OF SURFACE PRETREATMENT OF BODIES OF NONCONDUCTIVE SYNTHETIC ELASTOMER MATERIAL TO IMPROVE THE ABILITY OF THAT SURFACE TO BE COATED OR ADHESIVELY BONDED COMPRISING ESTABLISHING AN ELECTRICAL POTENTIAL ACROSS AN ANODE AND A CATHODE IN A BODY OF AQUEOUS ELECTROLYTE TO GENERATED AT SAID ANODE, PRODUCTS OF ELECTROLYSIS REACTIVE WITH SAID ELASTOMER TO FORM REACTION PRODUCTS MORE READILY WET AND BONDED BY COATINGS AND ADHESIVE COMPOSITIONS, SAID ANODE BEING SUBSTANTIALLY INERT TO PRODUCTS OF ELECTROLYSIS GENERATED AT SAID ANODE, DISPOSING THE SURFACE TO BE TREATED IN SAID BODY OF ELECTROLYTE CLOSELY ADJACENT TO SAID ANODE FOR ENGAGEMENT AND REACTION WITH SAID PRODUCTS OF ELECTROLYSIS AS THEY ARE FORMED AND MAINTAINING SAID SURFACE ADJACENT SAID ANODE FOR A PERIOD FOR REACTION OF THE ELASTOMER AT SAID SURFACE WITH PRODUCTS OF ELECTROLYSIS GENERATED AT SAID ANODE TO FORM ON SAID BODY A SURFACE OF REACTED ELASTOMER INTEGRAL WITH THE ELASTOMER OF

5. A shoe making process in which a surface to be adhesively bonded of a tread member of synthetic elastomeric material is disposed adjacent an anode in a body of aqueous inorganic halide electrolyte, an electrical potential is established between said anode and a cathode in said body of electrolyte to generate at said anode products of electrolysis including a halogen reactive with said elastomer to form reaction products more readily wet and bonded by tread member attaching adhesive compositions, said anode being substantially inert to said products of electrolysis, said surface is maintained closely adjacent to said anode for a period for reaction of the elastomer at said surface with said products of electrolysis as they are generated at said anode, the tread member is removed from said body of electrolyte, unwanted residue from the electrolytic treatment is removed, and an adhesive composition is applied to the tread member.
