WebbCellulose ether polymers are used by the paint industry as thickening agents for waterborne paints. Reduction in their degree of polymerization results in the loss of paint viscosity (paint thinning).9 Endoglucanases hydrolyze at random the 1,4-linkage in the cellulose ether chains. These enzymes cause a rapid drop in substrate viscosity ... WebbBerolan starch ethers are modified starches derived from potato, corn, tapioca, and wheat. They can be used for plasters (to improve stability and facilitate screeding), tile … Webb11 sep. 2024 · Different from the cleavage of hydroxypropyl and hydroxyethyl starch [7,9,21] or cellulose ethers , the procedure of displacement reaction of 4-hydroxybutyl starch ether was slightly complicated .
