Abstract

Polymères modifiés chimiquement Les polymères de base sont des esters ou des éthers de la cellulose, l'alcool polyvinylique ou ses esters, des copolymères d'esters vinyliques, ainsi que des homopolymères et copolymères d'acrylates et de méthacrylates. Après modification, ils renferment des radicaux de beta -oxo-acides cycliques monofonctionnels ou difonctionnels, par exemple des radicaux d'acides succinylo-succiniques de formule :
