标题:One step synthesis of ultrahigh molecular weight block copolymers
发明人：URBAN MAREK W
权利人:UNIV CLEMSON; UNIV CLEMSON RES FOUNDATION
摘要:Single-step synthesis processes for production of ultrahigh molecular weight block copolymers are described. The ultrahigh molecular weight copolymers can have a molecular weight of about 10 6 or greater and can be formed within a few hours in a surfactant-free environment. The formation process is controlled by initiator-starvation conditions in a sequential polymerization of monomers exhibiting different solubility in the solvent.

标题 :Hydrogenation of halogen-containing carboxylic anhydrides
发明人：NOVOTNY MIROSLAV
权利人:ALLIED CHEM
摘要:A process is described for the heterogeneous hydrogenation of haloalkyl, halocycloalkyl or haloaryl carboxylic anhydrides to the corresponding primary alcohols. In the haloalkyl or halocycloalkyl carboxylic anhydrides at least one halogen is in the alpha-position relative to the carboxylic anhydride grouping. The hydrogenation can be carried out in the liquid or vapor phase in the presence of a supported or unsupported catalyst comprising a member of the group consisting of rhodium, iridium, metal oxides thereof, or mixtures thereof. In the liquid phase, the hydrogenation can be carried out batchwise under mild conditions of temperature and pressure, preferably at about 50°-150° C. and about 5-15 atmospheres, in an atmosphere containing hydrogen gas. A preferred embodiment is the hydrogenation of trifluoroacetic anhydride in the liquid phase to 2,2,2-trifluoroethanol, said alcohol being useful as an intermediate in the synthesis of the anesthetic, isoflurane, CF 3 CHClOCHF 2 .
