Abstract

"éTER DE CELULOSE ANIÈNICA HIDROFOBICAMENTE MODIFICADA, E, USO DO MESMO". A invenção refere-se a um éter de celulose aniónica hidrofobicamente modificada obtenível por um processo compreendendo reação de uma celulose de metal alcalino com pelo menos três reagentes A, B e C. Reagente A é selecionado do grupo consistindo de ácidos halo-acéticos, halo-acetatos de metal alcalino, vinil-sulfonatos de metal alcalino, e ácido vinil-sulfónico. Reagente B possui a fórmula R^ 1^- (OCH~ 2~CH(R^ 2^))~ n~-P, na qual R^ 1^ representa um grupo C~ 2~-C~ 7~, R^ 2^ é hidrogênio ou um grupo metila, n é 0-2, e P representa um grupo glicidil-éter, um, grupo 3-halo-2-hidróxi-propil-éter, um grupo 1,2-epóxi, ou um halogeneto, e reagente C possui a fórmula R^ 3^-(OCH~ 2~CH(R^ 2^))~ m~-P, na qual R^ 3^ representa um grupo C~ 8~-C~ 30~, m é 0-10, e R^ 2^e P possuem o mesmo significado descrito acima.
