Abstract
PROCEDE POUR TRANSESTERIFIER DES ESTERS ALKYLIQUES D'ACIDES MONOCARBOXYLIQUES OU POLYCARBOXYLIQUES AVEC DES DIOLS ALIPHATIQUES OU CYCLOALIPHATIQUES QUI RENFERMENT AU MOINS 3ATOMES DE CARBONE. ON EFFECTUE LA TRANSESTERIFICATION EN PRESENCE DES QUANTITES CATALYTIQUEMENT EFFICACES D'UN OU PLUSIEURS ACIDES PHOSPHONIQUES REPONDANT A LA FORMULE: (CF DESSIN DANS BOPI) DANS LAQUELLE R REPRESENTE UN RADICAL HYDROCARBONE DE CARACTERE ALIPHATIQUE OU AROMATIQUE. EN POLYCONDENSANT LES PRODUITS DE TRANSESTERIFICATION AINSI OBTENUS ON PEUT PREPARER DES POLYESTERS AYANT UNE GRANDE STABILITE DE TEINTE.
