Title (EN) TRANSESTERIFICATION METHOD FOR MAKING CYANOACRYLATES
(FR) PROCEDE DE TRANSESTERIFICATION DESTINE A LA PREPARATION DE CYANOACRYLATES
Abstract:
(EN) An $g(a)-cyanoacrylate may be formed by first condensing a cyanoacetate with paraformaldehyde or formaldehyde; reacting the polymer formed with an alcohol to transesterify the polymer; and depolymerizing the polymer to form $g(a)-cyanoacrylate monomers.
(FR) Selon l'invention, on peut former un $g(a)-cyanoacrylate par condensation d'un cyanoacétate avec un paraformaldéhyde ou un formaldéhyde, puis en faisant réagir le polymère obtenu avec un alcool afin d'effectuer la transestérification dudit polymère, et en dépolymérisant ce polymère en vue d'obtenir des monomères de $g(a)-cyanoacrylate.
