Process for preparing amp;agr;-cyanoacrylate type compounds and adhesive composition comprising amp;agr;-cyanoacrylate type compound obtained by the process as its main component

摘要

A process for preparing an &agr;-cyanoacrylate compound characterized by the steps of thermally depolymerizing a condensation product obtained from a cyanoacetic acid ester, and formaldehyde or a polymer thereof using as a catalyst a polymerizable imine represented by the formula ##STR1## wherein R.sub.1 and R.sub.2 are the same or different and are each CH.sub.3 or H to obtain a crude monomer, and rectifying the crude monomer and an adhesive composition comprising as its main component an &agr;-cyanoacrylate compound prepared by the above process.
