The present invention relates to thermoplastic, water-insoluble and completely compostable cellulose ether esters, which are characterized by the general structure (I) be described in which Cell-O represents the substituted radical of a hydroxyl group on the cellulose chain and B is a polymeric ether group of structure (II), in which E represents an aliphatic, branched or unbranched chain having 2 to 4 carbon atoms, n is an integer from 1 to 5 and, if n is 0, at least one of the groups A is a methyl, ethyl, benzyl, carboxylalkyl, sulfoalkyl or cyanoethyl group and at least one of the groups A is a 2-hydroxycarboxylic acid of structure (III) - (EO) n - (III) D 1 and D 2 independently of one another represent a hydrogen atom or a methyl or ethyl group, m represents an integer from 1 to 10. |
