| 20100204361 | NOVEL MULTIFUNCTIONAL AZO INITIATORS FOR FREE RADICAL POLYMERIZATIONS: METHODS OF PREPARATION - The invention provides compositions of matter, methods of their synthesis, and methods of their use in polymerization reactions. The compositions include polyfunctional initiators used to make star polymers when polymerized with monomers. The polyfunctional initiators are synthesized out of a multifunctional core with at least two functional groups and two or more initiator units bonded to the functional groups. The initiator units have two electron-withdrawing groups bonded to a central carbon atom and an azo group between the central carbon atom and the functional group. The polyfunctional initiators are particularly effective because when they decompose to form the radical core of a star polymer, the electron-withdrawing groups prevent the corresponding radical from forming any linear polymer contamination and only desired star polymers result. | 08-12-2010 |

In addition when the desired star polymers are fed into a reaction vessel by streams with two different concentrations the star polymers produce superior properties. | 08-12-2010 |
| 20100249275 | SILICONE COMPOSITION EMULSION AND METHOD FOR PREPARING THE SAME - A silicone composition emulsion and a method for preparing the same are provided. The method is characterized in that a low-molecular-weight polysiloxane and an emulsifier are added into a high-viscosity silicone composition. The low-molecular-weight polysiloxane has a viscosity of 5-3,000 mPa·s, and the emulsifier is an nonionic surfactant. The amount of the low-molecular-weight polysiloxane is 5-50 parts and the amount of the emulsifier is 40-150 parts, based on 100 parts of the high-viscosity silicone composition. | 09-30-2010 |
| 20140011914 | METHODS AND DEVICES FOR CONTINUOUS PRODUCTION OF POLYMERIC DISPERSIONS - The present invention is directed to the use of continuous extrusion devices to form high quality polymer dispersions. Screw extruder devices of the present invention inject water into a zone of high pressure, temperature, and shear to cause the rapid inversion of a weld in less than, for example, one minute, which compares very favorably with conventional batch methods, which can take, for example, two or more hours to complete an inversion. This rapid inversion—a surprising result given the extended time inversion requires in batch processes—allows for the continuous production of polymer dispersions. | 01-09-2014 |
| 20150031794 | Method For In-Situ Synthesis Of Silicon Nanoparticles - The invention relates to a method for in-situ synthesis of silicon nanoparticles in a thermosetting polymeric matrix, the thermosetting and thermoset matrices obtained in this way and a material including same. The method includes the following steps: a) forming an aqueous-phase/organic-phase inverse emulsion, wherein the aqueous phase includes at least a basic catalyst and the organic phase includes at least a non-cross-linked (co)polymer precursor chosen from an aliphatic, cycloaliphatic or aromatic epoxy resin precursor, a polyester-imide precursor, an unsaturated/epoxy polyester (co)polymer precursor, a polyether/epoxy (co)polymer precursor and a polyurethane precursor; b) introducing, into the inverse emulsion formed in step a), at least one silicon precursor forming a complete network whereof the rate of hydrolysis is greater than the cross-linking speed of the (co)polymer and c) stirring the mixture obtained in step b) and heating to a temperature between 20° C. and 70° C. | 01-29-2015 |

| 20100063180 | FIRE PROTECTION AND/OR FIRE FIGHTING ADDITIVES, ASSOCIATED COMPOSITIONS, AND ASSOCIATED METHODS - Fire protection and/or fire fighting additives including a water-swellable polymer, a water immiscible phase, an emulsifier, an inverter, and a remainder water are disclosed. The water-swellable polymer is acrylamide-free and crosslinked and may be prepared by inverse phase polymerization. Such fire protection and/or fire fighting additives and fire protection and/or fire fighting compositions made using the additives exhibit exceptionally low corrosion properties. For example, when contacted with any one of a 2024-T3 aluminum alloy, 4130 steel, yellow brass, or AZ31B magnesium alloy, the corrosion rate is less than about 5 mils/yr for the fire protection and/or fire fighting additives. | 03-11-2010 |
| 20110245374 | Multiple Emulsions Containing Silicone Resin - W/O/W multiple emulsions are disclosed having improved stability against coalescence and phase separation. When a silicone MQ resin is incorporated in the oil phase, a multiple emulsion can be easily made without stringent requirements on other emulsifiers used in the system. | 10-06-2011 |
