标题:Superior solvent blends for synthesis of acrylic resins for high solids coatings
发明人：BOUBOULIS CONSTANTINE J; KUNTZ IRVING
权利人:EXXON RESEARCH ENGINEERING CO
摘要:According to the present invention, an improved method for providing acrylic copolymer resins is provided in which the polymerization solvent comprises a blend of methyl isobutyl ketone and certain alkyl-substituted benzene solvents. The monomers comprise hydroxy-substituted alkyl (meth)acrylate monomers and non-hydroxy substituted alkyl (meth)acrylate monomers, and the process provides an improved method for forming low molecular weight acrylic resins useful as components in acrylic coatings. The polymerization solvent can remain in the resin to become a solvent employed in the higher solids coating containing the thus-formed acrylic resins and provides improved electrical resistivity, improved solvency and decreased surface tensions over prior art polymerization solvents.

摘要:This invention is directed to novel crystalline solvates of the ( S )-P diastereomer of the anti- HCV nucleoside phosphoroamidate, (2 S )-neopentyl 2-((((2 R ,3 R ,4 R ,5 R )-5-(2-amino-6- methoxy-9H-purin-9-yl)-3,4-dihydroxy-4-methyltetrahydrofuran-2-yl)methoxy)(naphthalen- l-yloxy)phosphorylamino)propanoate (also referred to as INX-08189 or IÎ?Χ-189), and to a recrystallization method for separating the two diastereomers of INX-08189. In addition, this application relates to a novel stereoselective method for the preparation of either of the two diastereomers, and to the novel synthetic intermediates used in this stereoselective synthesis. The invention also relates to the use of the crystalline solvates to increase the liver exposure of 2'-C-methyl guanosine triphosphate from an oral dose.
