Abstract
An adhesive composition containing monomeric .alpha.-cyan acrylates - alkyl -.alpha.-cyan acrylates having from 1 to 7 carbon atoms, and/or allyl-.alpha.-cyan acrylate, as well as a modifying additive comprising fluorinated methacrylate or fluorinated acrylate of the general formula ##STR1## wherein n=1-3, R is H, CH.sub.3, or CH.sub.2 --C-- COOH.sub.2 (CF.sub.2)n.sub.1 CF.sub.3, wherein n.sub.1 =1-2 and R has the abovementioned significances. Monomeric .alpha.-cyan acrylates are used in an amount of 70-90 w.% and the modifying additive in an amount of 10-30 w.%. A strength of adhesive bond obtained using the adhesive compositions according to the invention attains 180-190 kp/cm.sup.2. The adhesive bond exhibits a considerable flexibility and hydrolytic stability.
