ABSTRACT:
Disclosed is an adhesive composition which contains (1) a polymer selected from acrylonitrile/butadiene copolymers, carboxyl group-containing acrylonitrile/butadiene copolymers, acrylic rubbers, urethane rubbers, chloroprene rubbers, chlorosulfonated polyethylene, ethylene/vinyl acetate copolymers, ethylene/acrylic acid or its ester or metal salt copolymers, ethylene/methacrylic acid ester or metal salt copolymers, thermoplastic polyurethanes, saturated polyesters and polyamides, (2) an epoxy acrylate resin, (3) an acrylic or methacrylic monomer having at least two different functional groups and/or an acrylic or methacrylic monomer of the formula: ##STR1## wherein R.sub.1 is H or CH.sub.3 and R.sub.2 is (C.sub.1 -C.sub.18) alkyl or an organic residue containing an aromatic hydrocarbon ring or a heterocyclic ring, (4) an organic peroxide and (5) an imidazole or an amino compound containing at least one tertiary amino group. The adhesive composition may further contain (6) a phosphorus-containing acrylate or methacrylate and/or a nitrogen-containing acrylate or methacrylate, and/or (7) an electroconductive material selected from carbon black having a surface area of 125 to 260 m.sup.2 /g and a DBP oil absorption of 100 to 200 cc/100 g, Ketjenblack, lamp black, acetylene black and graphite, and a cut carbon fiber and fine powders of aluminum, nickel, copper and zinc, having a size of not larger than 200 mesh. A structural adhesive is prepared by impregnating, spread-coating or laminating a strand mat, surface mat, cloth, nonwoven fabric or victoria lawn, composed of a glass fiber, a glass fiber/organic fiber composite, an organic fiber or a carbon fiber with the adhesive composition.
