Abstract
Se preparan dos o más ésteres de un éter de celulosa, cada uno teniendo los mismos sustituyentes éter y éster pero diferentes pesos moleculares promedio en peso en un procedimiento, el cual comprende los pasos de esterificar un éter de celulosa con (i) un anhídrido de ácido monocarboxílico alifático, o (ii) un anhídrido de ácido dicarboxílico, o (iii) una combinación de un anhídrido de ácido monocarboxílico alifático y un anhídrido de ácido dicarboxílico en presencia de un ácido carboxílico alifático como un diluyente de reacción en dos o más reacciones separadas, en donde en cada reacción se utiliza una relación molar diferente [unidades de ácido carboxílico alifático/anhidroglucosa de éter de celulosa] para producir ésteres del éter de celulosa de diferentes pesos moleculares promedio en peso.
