The aqueous solution is dispersed in an organic medium containing a surfactant. This leads to gelation in individual droplets. The crosslinking in individual ... 11/09/06 - 20060252887 - Method of increasing the absorption rate of peroxides into polymer particles The present invention provides a method of increasing the absorption rate of peroxides into polymer particles used to fabricate electrical cable insulation. The method includes contacting the polymer particles with a peroxide compound and an additive under physical mixing conditions at a temperature that is above the melting point of ... 08/24/06 - 20060189766 - Aminomethyl polystyrene resin and preparation process for the same The present invention relates to an aminomethyl polystyrene resin wherein aminomethyl group is grafted only on the surface of polystyrene resin, and a preparation process for the same. More particularly, the present invention is directed to a process for preparing aminomethyl polystyrene resin wherein aminomethyl group is grafted only on ... 08/17/06 - 20060183866 - Blocked mercaptosilane coupling agents for filled rubbers Blocked mercaptosilanes are provided in which the blocking group contains an unsaturated heteroatom or carbon chemically bound directly to sulfur via a single bond. This blocking group optionally may be substituted with one or more carboxylate ester or carboxylic acid functional groups. These silanes are used in manufacture of inorganic ... 07/06/06 - 20060148998 - Solid reagents An object of the present invention is to provide a novel solid reagent capable of solving the problems of conventional solid reagents based on resin beads. The present invention relates to a solid reagent comprising an organic polymer base in which a polymer side chain is introduced onto the backbone ... 08/04/05 - 20050171291 - Method of preparing propionic acid-terminated polymers The invention provides methods for preparing polymers bearing a terminal propionic acid. The method involves first reacting a water soluble and non-peptidic polymer comprising at least one hydroxyl group with a tertiary alkyl acrylate in the presence of a catalyst to form a propionic acid ester of the polymer, wherein ... 06/30/05 - 20050143528 - Recovery of antimony catalyst residues from bromination reaction mixtures A process for brominating a styrenic polymer in an organic solvent in the presence of an antimony trihalide catalyst such that a reaction mass containing brominated styrenic polymer in an organic phase is formed is improved by mixing hydrochloric acid or hydrobromic acid, or both, with said reaction mass at ... 06/30/05 - 20050143527 - Aqueous resin dispersion composition and process for producing the same The present invention provides an aqueous resin dispersion composition prepared by neutralizing an acid-modified chlorinated polyolefin with a basic substance and dispersing the neutralized acid-modified chlorinated polyolefin in water; and a process for producing an aqueous resin dispersion composition comprising the steps of dissolving an acid-modified chlorinated polyolefin in an ... 06/02/05 - 20050119416 - Arene-ruthenium complexes immobilized on polymers, catalysts consisting of the complexes, and processes for organic syntheses with the same wherein A represents an organic polymer with a side chain containing an aromatic ring coordinated to Ru, X1 and X2 represent the same or different halogen atoms, and R represents a hydrocarbon group that may have a substituent is provided for use as a catalyst. This novel polymer-supported arene-ruthenium complex ... ### FreshPatents.com Support |
