A pressure sensitive adhesive polymer electrolyte having a peel adhesion by test A of more than 1 N/cm and an ionic conductivity by test B of more than 10.sup.−6 (ohm*cm).sup.−1, prepared by polymerizing: 5-60 wt % of acrylate monomer from the group of the (meth)acrylic esters having 4-15 carbon atoms, which as a homopolymer would have a T.sub.g by test C of less than −30° C., 10-80 wt % of acrylate monomer from the group of the (meth)acrylic esters having 4-25 carbon atoms and containing at least one heteroatom, which as a homopolymer would have a T.sub.g by test C of less than 100° C., 0.05-10 wt % of initiator, 2-13 wt % of conducting salt, optionally plasticizer, and optionally solvent, which after the polymerization is typically removed at least partly,
where optionally one or more of the components are added at least proportionally only during or after the polymerization.

This invention relates to cyanoacrylate-containing compositions that include (a) a beta-alkoxy cyanoacrylate component, (b) a cyanoacrylate component selected from butyl cyanoacrylates, octyl cyanoacrylates, and combinations thereof; (c) a rubber toughening component (d) a surface modified component; and (e) an adhesion promoter. Cured products of the inventive cyanoacrylate compositions demonstrate improved toughness without an odor typically found with cyanoacrylate-containing compositions.
