Abstract: Cellulose ether derivatives comprising a hydrophobic substituent having an unsaturated alkyl portion are disclosed. The unsaturation in the alkyl portion of the hydrophobic substituent can promote crosslinking of the cellulose ether derivative. The cellulose ether derivatives are useful as ingredients in latex compositions. The cellulose ether derivatives can provide associative thickening and rheological properties to latex composition during storage and application. In addition, after the latex composition is applied to the surface to be coated, the cellulose ethers of the present invention can promote crosslinking of the latex film to provide a hard and durable coating. Latex paint compositions comprising the cellulose ether derivatives of the present invention are also disclosed.

Abstract: 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.

Abstract: A manufacturing method for cellulose ether having a high degree of substitution characterized in that an etherifying agent represented by a general formula RCH.sub.2 X (where R is aromatic group, heterocyclic group, vinyl group or ethynyl group or the same group substituted and X is chlorine or bromine) is reacted with a uniform solution of cellulose acetate having a degree of substitution of 2.0 and over in an organic solvent in the presence of a base to manufacture a highly substituted cellulose ether having a degree of substitution of 2.0 and over per anhydrous glucose unit by a one stage reaction at a good yield.As a general method for manufacturing cellulose ether, a method for reacting an etherifying agent with alkali cellulose is now in use. For the general method, several improved methods have been proposed. However, it is difficult to manufacture cellulose ether having a degree of substitution of 2.5 and over by a one stage reaction using the general method. As manufacturing methods for cellulose ether other than the general method, a method for using a solvent-soluble cellulose derivative as the raw material and a method for using a special solvent in which cellulose is soluble were proposed. However, the former had a defect of a low yield and the latter had a defect of too long a reaction time.

Abstract: In accordance with some embodiments of the present invention, a composite material is prepared by blending a flame retardant modified cellulosic nanomaterial (FR-CN) filler into a polymer, wherein the FR-CN filler comprises a cellulosic nanomaterial (e.g., cellulose nanocrystals (CNCs) and/or cellulose nanofibrils (CNFs)) having a surface functionalized to incorporate a phosphorus-containing moiety. In some embodiments, the FR-CN filler is prepared by reacting hydroxyl groups on the surface of the cellulosic nanomaterial and a halogenated phosphorous-containing monomer (e.g., diphenyl phosphoryl chloride). In some embodiments, the surface of the cellulosic nanomaterial is further functionalized to incorporate an orthogonal functionality selected to enhance the compatibility of the FR-CN filler with the polymer by reacting hydroxyl groups on the surface of the cellulosic nanomaterial and a monomer (e.g., epichlorohydrin when the polymer is an epoxy-based polymer).
