A process for producing a crosslinked cellulose ether including the steps of (i) contacting at least one cellulose material with a mixture comprising (ia) at least one crosslinking agent and (ib) at least one alkalization reagent to form an activated cellulose material; and (ii) contacting the activated cellulose material of step (i) with at least one etherification reagent; wherein the at least one etherification reagent reacts with the activated cellulose material to form the crosslinked cellulose ether; and a crosslinked cellulose ether produced by the above process.

The present disclosure relates to a method for manufacturing carboxymethyl cellulose particles, cellulose inducer particles manufactured by the method, and an absorbent article comprising same. The method comprises: (1) a step of obtaining alkalized cellulose by reacting a cellulose raw material with an alkalizer; (2) a step of obtaining carboxymethyl cellulose by reacting the alkalized cellulose with a carboxy methylating agent; (3) a primary cross-linking step of obtaining a slurry-phase carboxymethyl cellulose cross-linked body by reacting the carboxymethyl cellulose with a core cross-linker; (4) a step of washing and dehydrating after filtering the slurry-phase carboxymethyl cellulose cross-linked body; (5) a secondary cross-linking step of obtaining carboxymethyl cellulose having a core-shell structure by reacting the carboxymethyl cellulose cross-linked body having undergone Step (4) with a surface cross-linker; and (6) a step of obtaining carboxymethyl cellulose particles having a core-shell structure by drying and pulverizing the carboxymethyl cellulose having a core-shell structure.

A method of simultaneously modifying degradation rates of at least two compounds including a first compound having a first unmodified degradation rate constant k.sub.1 and a second compound having a second unmodified degradation rate k.sub.2 is provided. The method includes combining a first composition including the first compound with a second composition including the second compound, degrading the first compound and forming a first degradation product; and degrading the second compound and forming a second degradation product. The second degradation product modifies the first unmodified degradation rate constant k.sub.1 of the first compound to a first modified degradation rate k.sub.1′ and the first degradation product modifies the second unmodified degradation rate k.sub.2 of the second compound to a second modified degradation rate k.sub.2′. Compositions resulting from the method are also provided.

Compositions of matter that are useful in the preparation of plastics and paints. These compositions contain a large number of silanol groups bonded to the silicon atoms that provide water solubility and/or disperseability of such materials in aqueous solutions. In addition, these compositions contain organofunctional groups that are antimicrobial in nature. These compositions, when coupled with plastics and paints, provide antimicrobial properties to such plastics and paints as well as adhesion properties.

The invention relates to a method for the preparation of a polymer hydrogel, comprising cross-linking a precursor comprising a hydrophilic polymer optionally in combination with a second hydrophilic polymer, using a polycarboxylic acid as the cross-linking agent. The invention further concerns the polymer hydrogel obtainable by the method of the invention and the use thereof in a number of different applications.
