Compositions for increasing corn oil recovery and embodiments of methods for using the composition for corn oil separation are described. The composition(s) incorporate an admixture that includes a polymer selected from a polyglycol ester, a polyethyleneoxide-polypropyleneoxide block copolymer, a poloxamine, or a mixture thereof. The methods include admixing the compositions with a process stream for, for example, the extraction of oil from milled corn and residues from a fermentation step, including stillage (e.g., thin stillage or mid stillage), distiller's wet grain, distiller's dry grain and distiller's dry grains with solubles.

This invention relates to an in-situ formed polyether polyol blend having an overall functionality of 2 to 3 and an overall hydroxyl number of 40 to 220 mg KOH/g. A process for preparing these in-situ formed polyether polyol blends is also disclosed. These in-situ formed polyether polyol blends are suitable for a process of preparing viscoelastic flexible polyurethane foams.

Some variations provide a multiphase polymer composition comprising a first polymer material and a second polymer material that are chemically distinct, wherein the first polymer material and the second polymer material are microphase-separated on a microphase-separation length scale from about 0.1 microns to about 500 microns, wherein the multiphase polymer composition comprises first solid functional particles selectively dispersed within the first polymer material, and wherein the first solid functional particles are chemically distinct from the first polymer material and the second polymer material. Some embodiments provide an anti-corrosion composition comprising first corrosion-inhibitor particles or precursors selectively dispersed within the first polymer material, wherein the multiphase polymer composition optionally further comprises second corrosion-inhibitor particles or precursors selectively dispersed within the second polymer material. These multiphase polymer compositions may be used for other applications, such as self-cleaning, self-healing, or flame-retardant coatings. Methods of making and using these multiphase polymer compositions are disclosed.

The present invention relates to a kind of organic metal-free catalysts containing both electrophilic and nucleophilic dual-functions, preparation methods of making the same, and uses thereof. The organic metal-free catalysts in the present invention have the chemical structure shown in formula (I):

##STR00001##

Compared with the metal-free organic polymerization catalytic systems that have been reported before, the organic metal-free catalysts in this invention have the combined advantages of simple preparation, high reactivity, easy operation, low cost, wide applicability, easy for industrial production.

The present invention relates to the purification of poloxamers to be used as cell culture media additives. Activated carbon can be used to remove hydrophobic high molecular weight components which reduce the efficacy of poloxamers as cell culture additives.

Methods of inhibiting microbes from attaching to a surface and anti-adherent compositions are disclosed. One method can include providing an anti-adherent composition that includes an anti-adherent agent configured to inhibit microbes from attaching to the surface. The anti-adherent agent can be: Acrylates Copolymer, Trimethylpentanediol/Adipic Acid/Glycerin crosspolymer, Trimethylpentanediol/Adipic Acid Copolymer, Ethylhexyl Stearate, Ethylhexyl Salicylate, Acrylates/C12-22 Alkylmethacrylate Copolymer, Octocrylene, Ethylene Oxide/Propylene Oxide Block Copolymer, Polyquaternium-101, or any combinations thereof. The method can include applying the composition to the surface and allowing at least some of the composition to remain on the surface such that the anti-adherent agent inhibits microbes from attaching to the surface. The anti-adherent composition can include a humectant and can be non-antimicrobial.
