标题:Process for the synthesis of silylated polyurethanes and silylated polyurethane composition
发明人：LAFERTE OLIVIER
权利人:BOSTIK SA
摘要:The present invention provides a process for the synthesis of silylated polyurethanes, comprising three sequential steps, a step (i) of preparing NCO-terminated polyurethane, a step (ii) of partial grafting of the NCO functions with silane functions and a step (iii) of total grafting of the residual NCO functions with functions that react with the NCO functions by means of polyfunctional compounds. The present invention also provides a silylated polyurethane composition that can be obtained by means of the process according to the invention, an adhesive composition comprising said silylated polyurethane composition and a self-adhesive item obtained from the adhesive composition according to the invention.

标 题:Catalyst for synthesis of vesicular phenoxy resins
发明人：BENNETT EVERETT W
权利人:JAMES RIVER PAPER CO
摘要:A catalyst for synthesis of vesicular phenoxy resins is disclosed. The catalyst includes a water-insoluble complex of a hydric phenol and a quaternary ammonium or phosphonium salt of the hydric phenol. Preferably, the hydric phenol is an intermediate of the phenoxy resin being produced. Dihydric phenols, such as sulfonyldiphenol are preferred. The invention further relates to a reaction medium for polymerization of phenoxy resins including the above-described catalyst and a solvent medium capable of dissolving the phenoxy resins and otherwise not interfering with the polymerization reaction. The solvent medium is advantageously free of toxic Methyl Cellosolve.

标 题:Process for the synthesis of isophorone in the liquid phase, including recycling of the by-products
发明人：RUPPIN CHRISTOPHE
权利人:ARKEMA FRANCE
摘要:The present invention relates to a continuous process for the synthesis of isophorone in the liquid phase by alkaline self-condensation of acetone, comprising the following successive steps: a) continuously injecting, through a tubular reactor (R), a stream of an aqueous alkali hydroxide solution and a stream of an organic solution comprising acetone and by-products recycled in step g), followed by b) condensation reaction of the acetone in the tubular reactor (R), then c) distillation of the reaction mixture from the tubular reactor (R), then d) separation of the concentrated raw reaction product from the distillation of step c), resulting in an alkaline aqueous phase and an organic phase containing isophorone, then e) distillation of the organic phase containing the isophorone recovered in the preceding step, then f) distillation of the polycondensation sub-products from the bottom of the column (D2) from the preceding distillation, then g) recycling, to the tubular reactor (R), of the stream from the column head of the preceding distillation (D3), said stream comprising xylitones and/or isoxylitones.
