  • Patent number: 7973089
    Abstract: The invention relates to a process for the extrusion of thermoplastic polymers having alkaline ionic groups. The process consists in preparing a mixture composed of a thermoplastic polymer having alkaline ionic groups and a plasticizer, in extruding the mixture obtained to form a film; then in washing the film obtained in aqueous medium to remove said plasticizer(s). The plasticizer is chosen from non-volatile compounds which are stable with respect to the ionic groups of the polymer, which are soluble in water or in solvents that are miscible with water, said plasticizers being chosen from the compounds that react with the ionic group of the polymer via formation of a weak bond of the hydrogen bond-type, and the compounds that react with the ionic group of the polymer via formation of a strong bond, of the ionic bond-type.

  • Patent number: 7968510
    Abstract: The present invention relates to benefit agent containing delivery particles, compositions comprising said particles, and processes for making and using the aforementioned particles and compositions. When employed in compositions, for example, compositions for cleaning, fabric care, or coating onto various substrates, textiles or surfaces, such particles increase the efficiency of benefit agent delivery, thereby allowing reduced amounts of benefit agents to be employed. In addition to allowing the amount of benefit agent to be reduced, such particles allow a broad range of benefit agents to be employed.

  • Patent number: 7943067
    Abstract: The present invention includes a method for preparing polymer hydrogel spherical particles on a nanometer scale (nanogels). The method includes encapsulating hydrogel-forming components into liposomes, diluting the large unilamellar liposomes suspension to prevent polymerization outside the liposomes, and polymerizing the encapsulated hydrogel-forming components. The lipid bilayer may be solubilized with detergent. The phospholipid and detergent molecules and their micelles may then be removed by dialysis. The resulting nanogels may then be dried by evaporation in a temperature gradient. Poly(acrylamide), poly(N-isopropylacrylamide), and poly(N-isopropylacrylamide-co-1-vinylimidazole) hydrogel particles with a diameter from 30 to 300 nm were detected and characterized by dynamic light scattering technique. The solvent, temperature, pH, and ionic sensitivities of the nanogels were studied.

  • Patent number: 7943676
    Abstract: A method of recycling waste plastic foam materials firstly is to smash a waste material including polyurethane foam into fine particles so as to obtain a first starting material. The first starting material is then crisped and followingly milled into powder so as to obtain a second starting material. The second starting material is then placed into a mixer to mix with a first foaming reaction solution including polyol, catalyst and additives injected into the mixer so as to form a semi-treated foaming material. And then, the semi-treated foaming material is mixed with a second foaming reaction solution including diisocyanate injected into the mixer so as to obtain a completed-treated foaming material. Lastly, the completed-treated foaming material is poured into a mold and then water vapor is uniformly introduced into the mold so as to induce the completed-treated foaming material to proceed foaming reaction.
