The present disclosure provides a biodegradable super absorbent polymer including a crosslinked polymer of a monomer including a modified polysaccharide having a maleic acid group (—OCOCH═CHCOOH) and a sulfosuccinic acid group (—OCOCH(SO.sub.3H)CH.sub.2COOH), which exhibits excellent biodegradability without deterioration in physical properties of the super absorbent polymer such as centrifuge retention capacity and absorbency under pressure, and a method for producing the same.

This invention relates to the use of destructured starch derivatives as hysteresis reduction additive in elastomer compositions and elastomer compositions containing those derivatives.

This invention relates to new destructured starch derivatives and elastomer compositions containing them. In particular this invention relates to destructured starch silyl ethers in which at least one oxygen atom of the destructured starch is covalently bonded to at least one silicon atom and/or to at least one compound containing silicon.

The present disclosure relates to charge-bearing polymeric materials and methods of their use for purifying fluid samples from micropollutants, such as anionic micropollutants.

Cationic and silicon substituents are introduced into polysaccharides thereby producing modified polysaccharides cationically substituted by quaternary ammonium groups and having a charge density of about 0.1 to about 2.5 meq/g, and further substituted by siliconate groups such that the modified polysaccharide has a silicon content of about 300 to about 5000 ppm. The modified polysaccharides have application in industrial, home care and personal care surface modifying formulations.

Layered, and optionally dispersible fibrous structures containing fibrous elements that exhibit different physical characteristics, such as different average diameters as measured by the Average Diameter Test Method described herein, different surface characteristics, different lengths, different sources (naturally occurring versus non-naturally occurring and/or spun versus non-spun), sanitary tissue products employing such layered, dispersible fibrous structures, and methods for making same are provided.

Described herein is an ethoxylated starch crosslinked with a cross linking agent having surprisingly high viscosity in water. The ethoxylated crosslinked starch described has a degree of ethoxy substitution from 1% to 3% and the crosslinking agent is from 0.02% to 0.05% of the weight of starch. Within this narrow range of values, a 7% wt/wt aqueous solution of the crosslinked ethoxylated starch exhibits a viscosity of at least 1600 cps at 95 ° C. This ethoxylated crosslinked starch is particularly useful in the formation of ceiling tiles with stucco, borax and steel wool, and should be useful in enhancing the viscosity of hydraulic fracturing fluids.

Disclosed is a processing method of a self-reinforced starch-based multifunctional material, and belongs to the technical field of starch deep processing. The processing method takes bulk starch as a base material, including the following steps: firstly reacting starch nanoparticles with an organic acid anhydride reagent and adding a bacteriostatic agent to prepare composite nanoparticles, then mixing the composite nanoparticles with the bulk starch, an etherifying agent, a crosslinking agent, a plasticizer and the like, and finally preparing a starch-based multifunctional material by dry extrusion modification combined with a starch-based nanoparticle assembly and reinforcement technology. The method of the disclosure is simple and convenient in step, mild and controllable in reaction, and continuous and green in production. The obtained product has good mechanical properties, high barrier properties and high antibacterial properties, can be applied to many fields such as food, textiles, daily chemicals and medicine, and has a broad market prospect.
