Nonionic cellulose ether with improve thickening properties

摘要

The present invention relates to associative cellulose ethers with improved thickening effects, especially in paint. The improvement depends on the presence of a hydrophobic modifying group of the general formulawhere R is an aliphatic group of 12-22 carbon atoms and n is a number from 3 to 7. The DS of the hydrophobic group is 0.003 to 0.012.
