摘要：

A kind of composition include the esterified cellulose ether of group a) comprising aliphatic unit price acyl group and formula C (O) R COOH R is bivalent hydrocarbon radical wherein I) degree of neutralization of group C (O) the R COOH is not more than 0.4 and II) total ester degree of substitution is 0.03 to 0.70 and b) there is the cellulose ether of 1.2 to the 200mPa.s viscosity measured in the form of 2 weight % aqueous solutions at 20 DEG C, the composition gelation and shows reduced syneresis when further increasing the temperature of gel at elevated temperatures.
