Abstract
L'invention concerne des éthers de carboxyméthylcellulose avec comme substituants des groupes de la formule (I) R-(A)m-(B)n-. Dans cette formule, R est un groupe C1-C30 alkyle ou alcényle droit ou ramifié, A est un groupe oxyalkylène O-CpH2p droit ou ramifié, p valant 2-4, B est -CH(OH)-CH2- uniquement quand m est égal à 0 ou B est -O-CH2-CH(OH)-CH2, m est égal à 0-20 et n est égal à 0-1. Le degré de substitution par les groupes alkyle va de 0,01.10?-2 à 2.10-1¿. Ces composés sont utiles comme épaississants pour les compositions aqueuses, en particulier pour les peintures, les plâtres et les produits cosmétiques.
