摘要： Cellulose ethers are disclosed which have sufficient nonionic substitution to render them water soluble and which are further modified with a C.sub.10 to C.sub.24 long chain alkylaryl group in an amount between 0.2% by weight and the amount which makes them less than 1% by weight soluble in water. Hydroxyethylcellulose is a preferred water soluble cellulose ether for modification according to the invention. These products exhibit substantially improved viscosifying effects compared to their unmodified cellulose ether counterparts, and provide good leveling and sag resistance in latex paints. Preferred alkylaryl groups are nonylphenyl, dodecylphenyl, and dinonylphenyl. Included are cellulose ethers with spacer groups of various lengths between the alkylaryl group and the connecting group to the cellulose molecule.

摘要： A novel phosphated, oxidized starch having a molecular weight of about 1,500 to about 40,000 Daltons, a carboxyl degree of substitution of 0.30 to 0.96, and a phosphate degree of substitution of from about 0.002 to about 0.005, which is useful as a dispersant for aqueous, high-solid slurries of minerals and inorganic pigments, as a replacement for gum arabic in gumming and fountain solutions for lithography, and as a drilling fluid additive.

摘要： This invention provides a cigarette product which releases vanillin or ethylvanillin aroma in sidestream smoke under cigarette smoking conditions. The paper wrapper of the cigarette product has a content of a flavorant-release additive which is a novel 3-vanillyl-2-hydroxypropyl or 3-ethylvanillyl-2-hydroxypropyl substituted ether derivative of cellulose.
