| 20090326149 | BRANCHED POLYCARBONATES AND PROCESSES FOR PRODUCING THE SAME - Methods for making a branched polycarbonate are disclosed. An interfacial mixture comprising water, a substantially water-immiscible organic solvent, a dihydroxy compound, a polyhydric branching agent, an endcapping agent, a catalyst, and a base is formed. The base and the branching agent are dissolved in the mixture before the dihydroxy compound is added, and the interfacial mixture has a basic pH. The mixture is reacted by adding a carbonate precursor to the mixture while maintaining the pH between about 8 and about 10 to form the branched polycarbonate. The resulting branched polycarbonates may contain more than 1.5 mole % of the THPE; have residual chloride content of 20 ppm or less; and a weight average molecular weight of about 55,000 or less. They may also be highly transparent. | 12-31-2009 |

| 20100130679 | METHOD FOR PRODUCING AQUEOUS VINYL ESTER DISPERSIONS - The preparation of vinyl ester homo- or copolymers by emulsion polymerization is described. The process is performed in the presence of a polymerization-retarding component in at least two phases, the concentration of the vinyl ester monomer in the polymerization mixture in the first phase having been depleted by not more than 50% at the end of the first phase compared to the concentration of the vinyl ester monomer in the polymerization mixture at the start of the first phase, and the concentration of the vinyl ester monomer in the polymerization mixture in the second phase being depleted compared to the concentration at the end of the first phase. The retarding component is depleted during the first phase. In the second phase, the heat of reaction is removed by evaporative cooling. In the first phase, the emulsion polymerization is effected at temperatures up to the boiling point of the vinyl ester-water azeotrope, and, in the second phase, at temperatures above the boiling point of the vinyl ester-water azeotrope. | 05-27-2010 |
| 20110112246 | PROCESS FOR THE PREPARATION OF HYDROTHERMAL HYBRID MATERIAL FROM BIOMASS, AND HYDROTHERMAL HYBRID MATERIAL OBTAINABLE BY THE PROCESS - The present invention relates to a process for the preparation of hydrothermal hybrid material, in particular coal-like hybrid material from biomass. The process involves the heating of a reaction mixture comprising water, biomass and a copolymerizable compound, wherein the copolymerizable compound is added when preparing the reaction mixture, in a variant of the process, the biomass is converted to activated biomass in a first step, and the copolymerization of the activated biomass and a copolymerizable compound to give the hydrothermal, preferably coal-like, hybrid material is started by adding a polymerization initiator. The invention also relates to the hydrothermal hybrid materials obtainable by the processes as such, e.g. to aqueous dispersions thereof. By incorporating copolymerizable compounds, e.g. petrochemical compounds in the structure of the hydrothermal hybrid materials, the physical properties of the materials and the preparation process thereof can be controlled. | 05-12-2011 |
