Abstract

CES DERIVES DE GELATINE ONT 25 A 100 DE LEURS GROUPES HYDROXYLE SOUS UNE FORME SUBSTITUEE, NOTAMMENT ESTERIFIEE. APRES AVOIR FAIT REAGIR LA GELATINE EN MILIEU AQUEUX AVEC UN AGENT DE SUBSTITUTION DES GROUPES AMINE DE CELLE-CI, LA SUBSTITUTION DE CES GROUPES POUVANT ETRE TOTALE OU PARTIELLE, ON FAIT REAGIR COMPLEMENTAIREMENT LA GELATINE EN MILIEU AQUEUX AVEC DES ANHYDRIDES OU DES CHLORURES D'ACIDES ORGANIQUES INTRODUITS EN UNE QUANTITE TELLE QUE 25 A 100 DES GROUPES HYDROXYLE DISPONIBLES SOIENT ESTERIFIES. SI L'ON EMPLOIE DES ANHYDRIDES DE POLYACIDE, ON OBTIENT DES DERIVES DE GELATINE NON DEGRADES, PORTANT UN NOMBRE DE GROUPES CARBOXYLE QUI EST AU MOINS LE DOUBLE DE CELUI DE LA GELATINE INITIALE ET A HAUTE VISCOSITE. LE POUVOIR GELIFIANT DES GELATINES S'ETANT REVELE PROPORTIONNEL AU NOMBRE DE LEURS GROUPES HYDROXYLE LIBRES, LE PRESENT PROCEDE PERMET D'AJUSTER OU D'ANNULER A VOLONTE CE POUVOIR GELIFIANT. LES GELATINES A POUVOIR GELEFIANT REDUIT OU NUL, ET EVENTUELLEMENT SANS DEGRADATION ET A HAUTE VISCOSITE, SONT UTILES ENTRE AUTRES POUR LA PREPARATION DE SUBSTITUTS DU PLASMA SANGUIN, D'ADDITIFS ALIMENTAIRES, ET ONT DES APPLICATIONS DANS L'INDUSTRIE PHOTOGRAPHIQUE ET EN COSMETOLOGIE.
