| 20080214760 | TERMINATING AGENT FOR ANIONIC POLYMERIZATION - A terminating agent and a method for preparing an anionic polymer are provided. The terminating agent includes a carbohydrate, which is a solid substantially insoluble in a solvent and is used for terminating an anionic polymerization of a polymer. Another aspect of the method includes steps which provide an initiator for initiating an anionic polymerization, adding a terminating agent for terminating the anionic polymerization and forming a complex, wherein the terminating agent is a carbohydrate, and an alkali metal ion is removed by a solid-liquid separation process. | 09-04-2008 |
| 20090176951 | Atom transfer radical polymerization in microemulsion and true emulsion polymerization processes - The invention is directed to a microemulsion polymerization comprising adding a polymerization catalyst precursor, such as a transition metal complex in the higher of two accessible oxidation states, an ATRP initiator, and an organic solvent to an aqueous solution to form an emulsion. Radically polymerizable monomers and a reducing agent may then be added to the emulsion. The reducing agent converts the catalyst precursor to a catalyst for polymerization of the first monomer from the initiator. In certain embodiments the organic solvent may comprise radically polymerizable monomers. The aqueous solution may comprise a surfactant. Further embodiments are directed to an ah initio polymerization process comprising adding a polymerization catalyst precursor; an ATRP initiator, and an organic solvent to an aqueous solution to form an emulsion, wherein the organic solvent comprises second radically polymerizable monomers, adding a reducing agent to convert the catalyst precursor to a catalyst for polymerization of the first radically polymerizable monomer from the initiator; and adding first radically polymerizable monomers to the emulsion. | 07-09-2009 |
| 20100113724 | IMPRINTED POLYMERS - The present invention relates to molecularly imprinted polymers, methods for their preparation and use of said molecularly imprinted polymers in separation, chemical sensors, drug screening, catalysis and in regioselective and enantioselective synthesis. | 05-06-2010 |
| 20100190946 | METHOD FOR PRODUCTION OF VINYL CHLORIDE-BASED POLYMER BY SUSPENSION POLYMERIZATION - The present invention provides a method of preparing vinyl chloride polymer having excellent processability and high bulk density by the separate stepwise additions of vinyl chloride monomer during suspension polymerization. | 07-29-2010 |
| 20110130534 | HIGH-STRENGTH POLYHIPE MATERIAL, PROCESS FOR PREPARING THE SAME, EMULSION USEFUL FOR PREPARATION THEREOF AND ARTICLE FORMED OF SAID MATERIAL - The invention relates to a polyHIPE material provided with high mechanical strength, which material comprises at least one N-alkenyltriazole monomer and a cross-linking monomer in a weight ratio of cross-linking monomer/N-alkenyltriazole monomer of 1/100 to 60/100. | 06-02-2011 |
| 20130217846 | METHOD FOR PRODUCING WATER-ABSORBENT RESIN | 08-22-2013 |
| 20130303714 | BIODEGRADABLE ABSORBENT MATERIAL AND METHOD OF MANUFACTURE - Biodegradable graft copolymers derived from a carbohydrate and at least one α,β-unsaturated carboxylic acid derivative having superabsorbent properties are disclosed in addition to the substantially adiabatic polymerization process by which the graft copolymers are made. The methods disclosed can be carried out in a variety of currently available continuous commercial reactors. Polymerizations carried out with starch have surprisingly produced substantially quantitative yields of graft copolymer free of residual monomer produced as a moist copolymer. Product work-up typically involves an optional neutralization and drying. | 11-14-2013 |
