Cyanoacrylate adhesive composition

The present invention provides a process for producing 2-cyanoacrylic acid, characterized by subjecting a 2-cyanoacrylate and an organic acid to transesterification reaction. The 2-cyanoacrylic acid obtained by the process of the present invention is useful as a starting material for the preparation of polyfunctional 2-cyanoacrylates.

Cyanocrylate adhesive composition

A resin composition for a composite-type vibration-damping material which comprises a saturated copolyester having a weight average molecular weight of at least 10,000 and a softening point of 50.degree. to 150.degree. C. and a polyfunctional isocyanate compound as a cross-linking agent and which, when cross-linked, has a degree of gelation (degree of cross-linking) of at least 10% and a composite-type vibration-damping material produced by use of the resin composition, have excellent adhesive strength and formability. When the resin composition is admixed with a conductive substance, a vibration-damping material produced by use of the admixture has excellent spot-weldability in addition to the above-mentioned excellent properties.
