Patent number: 9090760
Abstract: Processes for continuously producing latex emulsions are disclosed. A multi-screw extruder is used for the production of the emulsion. A resin is fed into the extruder, heated, optionally dissolved in a solvent, mixed with a base to neutralize the resin and form particles, then mixed with a surfactant and water to form a phase inverted emulsion (PIE). The PIE may be sent to a distillation column to separate out the solvent, and the resulting latex emulsion is then sent to a receiving tank. These processes are useful for making precursors for toner compositions.

Patent number: 9078445
Abstract: Antimicrobial chemical compositions comprise an aluminum phosphate (AlP) solid dispersed within a binding polymer, wherein one or more bioactive materials are disposed within AlP forming a bioactive-AlP complex. The complex may comprise the bioactive material chemically bonded with the AlP, physically combined with the AlP, or a combination of both. The complex may be formed according to precipitation, condensation and sol-gel methods of forming. The complex is engineered to provide a controlled delivery of the bioactive material or a constituent thereof upon exposure to moisture to give a desired level of antimicrobial resistance to a film or composite formed from the composition of at least about 30 ?g/m2, and may also provide a desired degree of corrosion resistance through the release of passivating phosphate anion.

Patent number: 9074069
Abstract: Controllably degradable overgrips are provided, as well as methods of producing controllably degradable thermoplastic polyurethane. Methods comprise pre-blending a catalyst on a matrix, dispersing a specified amount of the pre-blended catalyst throughout solid granular thermoplastic polyurethane to yield a polymer component, and determining an onset timing of hydrolytic breakdown of the polymer component by adjusting the specified amount of dispersed catalyst. The thermoplastic polyurethane may be produced by reacting low molecular weight aliphatic diol(s) with aliphatic dicarboxylic acid(s) to produce polyester, and reacting the polyester with organic di-isocyanate(s) and diol chain extender(s) using catalytic amounts of alkali or alkaline earth metal salt(s) of C10 to C45 aliphatic carboxylic acid(s). Tackifying resins may be added to adjust an adhesive profile of the overgrips.

Patent number: 9062190
Abstract: A stone based copolymer substrate includes calcium carbonate (CaCO3) from approximately fifty to eighty-five percent (50-85%) by weight and varying in size generally from 1.0 to 3.0 microns, high-density polyethylene (HDPE) from approximately two to twenty-five percent (2-25%) by weight and a biopolymer from approximately two to twenty-five percent (2-25%) by weight. The substrate may include a biodegradation additive from approximately three fourths of a percent to two percent (0.75-2%) by weight. By selectively adjusting the ranges of the substrate's components, various products can be made to replace current tree-based and plastic-based products. The substrate can be configured to be tear proof, water proof, fade resistant and fire retardant while utilizing less energy and producing less waste during its manufacture. In an exemplary embodiment of the invention, the stone used in the substrate includes limestone.
