1. A method of bonding or adhering a first substrate to a second substrate, comprising interposing a composition between the first and second substrates, said composition comprising an ionomer and a polar carrier, wherein said carrier and said ionomer are blended substantially with one another and form a mixture, and wherein said ionomer and/or said carrier are present in amounts effective to allow said composition to be heated by RF energy;

  • and applying RF energy to said composition to heat said composition, thereby causing the first and second substrates to become adhered or bonded, with the proviso that said ionomer is not a quaternary ammonium salt or a sodium polystyrenesulfonate and said polar carrier is not water.
