摘要： The invention relates to a process for the manufacture of a cyclic oligo(arylene ether) which can be a cyclic oligo(dichloromethylene arylene ether) or a cyclic oligo(arylene ether ketone); the process comprises the step of causing an aromatic compound to react with a hexachloroxylene compound in a pseudo-high dilution environment. The invention relates also to new cyclic oligo(arylene ether)s and their use for the manufacture of acyclic poly (arylene ether)s, such as PEKK, by ring-opening polymerization.

摘要： A chemical blowing agent for foaming a thermoplastic polymer, for example PVC plastisol or a polymer resin in an extrusion process, said chemical blowing agent comprising a functionalized particulate bicarbonate containing at least one additive, preferably excluding an exothermic blowing agent. The additive may be selected from the group consisting of rosin acids, any derivative thereof, and salts thereof; or any combinations thereof, such as comprising abietic acid, dihydroabietic acid, neoabietic acid, a rosin acid ester, or mixtures thereof. The particulate bicarbonate may be preferably functionalized by spray-coating, extrusion or co-grinding with at least one additive. The functionalized particulate bicarbonate may comprise 50 wt % to less than 100 wt % of the bicarbonate component, and 0.02-50 wt % of the additive. The functionalized particulate bicarbonate may further comprise 0.1-5 wt % silica. A foamable polymer composition comprising such chemical blowing agent. A process for manufacturing a foamed polymer, such as foamed PVC, comprising shaping and heating the foamable polymer composition, and a foamed polymer obtained by such process.

摘要： Process P1 for the manufacture of a secondary fatty alcohol, said process P1 comprising synthesizing an internal ketone K1 by a process P0 comprising the decarboxylative ketonization reaction of a fatty acid or the like in a liquid phase with a metal compound as catalyst in a reaction medium, wherein a ketone K2 at liquid state, which is identical or similar to the internal ketone K1, is introduced into the reaction medium, and subjecting the internal ketone K1 to a hydrogenation reaction with hydrogen gas as hydrogenating agent to form the secondary fatty alcohol. Use of the secondary fatty alcohol manufactured by the process P1 for the manufacture of an internal olefin or of an internal olefin sulfonate.
