Abstract
A new nonionic, water-soluble cellulose ether, i.e., hydroxyethyl cellulose substituted with an alkylglycidyl radical wherein alkyl moiety is a straight or branched chain alkyl group containing 1 to 10 carbon atoms, and a building composition based on hydraulic or synthetic binder containing the new nonionic, cellulose ether are disclosed. The building composition has superior physical properties as compared to prior compositions containing other cellulose derivatives.
Claims15
A building composition comprising, based on the total weight of the composition, from about 2 to about 99 wt. % of at least one hydraulic or synthetic binder, up to about 95 wt. % of at least one filler, and from about 0.05 to about 5 wt. % of at least one nonionic, water-soluble 3-alkoxy-2-hydroxypropylhydroxyethylcellulose comprising about 0.05 to about 50%, based on the weight of the substituted hydroxyethyl cellulose, of at least one 3-alkoxy-2-hydroxypropyl group wherein the alkyl moiety is a straight or branched chain alkyl group having 1 to 10 carbon atoms.
A building composition comprising, based on the total weight of the composition, from about 2 to about 99 wt. % of at least one hydraulic or synthetic binder, up to about 95 wt. % of at least one filler, and from about 0.05 to about 5 wt. % of a nonionic, water-soluble 3-butoxy-2-hydroxypropylhydroxyethylcellulose comprising about 0.05 to about 50%, based on the weight of the substituted hydroxyethyl cellulose, of a 3-butoxy-2-hydroxypropyl group.
