COMPOSITIONS COMPRISING CELLULOSE ETHERS AND WATER-SOLUBLE ESTERIFIED CELLULOSE ETHERS

摘要

A composition comprising a) an esterified cellulose ether comprising aliphatic monovalent acyl groups and groups of the formula - C(O) - R - COOH, R being a divalent hydrocarbon group, wherein I) the degree of neutralization of the groups - C(O) - R - COOH is not more than 0.4 and II) the total degree of ester substitution is from 0.03 to 0.70, and b) a cellulose ether having a viscosity of from 1.2 to 200 mPa s, measured as a 2 weight-% aqueous solution at 20°C, gels at increased temperature and displays reduced syneresis when further increasing the temperature of the gel.
