The present invention relates to water-soluble, particularly ternary, preferably ionic, cellulose mixed ethers, more particularly to anionic water-soluble cellulose mixed ethers, as additives for drilling fluid applications.

Use of cellulose mixed ethers as additives for earth pressure shields

The present invention relates to carboxymethylcellulose (CMC) having a lower degree of substitution and to its use in textile printing.

Carboxymethylcellulose and its use in textile printing

The invention relates to certain highly substituted carboxymethyl sulfoethyl cellulose ethers (CMSEC), to a simplified and economic process for their production and to their use as thickeners in textile printing.

Highly substituted carboxymethyl sulfoethyl cellulose ethers (CMSEC), a

The present invention relates to sulphoalkylcellulose derivatives, in particular sulphoethylcellulose, with a degree of substitution by sulphoethyl groups of 1.2 to 2.0 using a one- to three-step, preferably two-step process and the use of the sulphoalkyl-cellulose derivatives as thickening agents or rheology improvers in textile printing.

Highly substituted sulphoalkycellulose derivatives, especially

The present invention relates to the use of anionic alkyl cellulose mixed ethers, preferably alkyl carboxy-methyl cellulose mixed ethers and, more preferably methyl carboxymethyl cellulose mixed ethers (MCMC), as auxiliaries in the textile industry and preferably as thickeners for textile printing pastes.

Use of anionic alkyl cellulose mixed ethers in textile printing

The invention relates to a new class of water-soluble ionic cellulose derivatives and their use as additive for gypsum- and cement-containing compounds.
