摘要： Cyanoacrylic adhesive compositions of the type comprising at least one cyanoacrylic acid ester or one malonic acid ester having an allyl, acrylic or methacrylic group, wherein there is also present at least one radical initiator of the polymerization reaction of the allyl, acrylic or methacrylic ester of cyanoacrylic acid or malonic acid and at least one radical inhibitor of said polymerization reaction. In comparison with known cyanoacrylic adhesive compositions, those according to the invention offer the advantage of maintaining their bonding capability even at high temperatures, in particular up to 150° C.
