    摘要: The present invention refers to a process for producing a polycarbonate diol, triol or polyol with increased molecular weight. The process comprises transesterification between a diol, triol or polyol and a carbon dioxide source in the presence of a transesterification catalyst, evaporation of formed alcohol by for instance distillation, polymerisation and further polymerisation by addition of an oligocarbonate diol, triol or polyol, whereby a polycarbonate diol, triol or polyol with an average molecular weight of at least 1000 g/mol is obtained, hi a further aspect, the use of a polycarbonate diol, triol or polyol obtained by the process as a building block in thermoplastic polyesters and polyurethanes is disclosed.

    摘要: A chain extended dendritic polyether comprising a dendritic core polymer and a chain extension bonded to said core polymer, which chain extended dendritic polyether optionally is at least partially chain terminated and/or partially functionalised. The core polymer is a polyhydric dendritic polyether and the chain extension is obtained by addition of at least one alkylene oxide to at least one hydroxyl group in said core polymer.

    摘要: The present invention relates to a process for producing potassium formate. Formaldehyde, potassium hydroxide and isobutyraldehyde are reacted in water, at a molar ratio of 1.0:1.0:1.0 to 3.0:2.0:1.0 and at a temperature of 0-1000C, preferably 30-700C. The obtained reaction solution is neutralised to pH 4-6 and evaporated in a first step, whereby two phases are obtained, one organic phase and one aqueous phase, the latter comprising the main part of the potassium formate. The organic phase is subsequently separated from the aqueous phase, where after a final evaporation of the aqueous phase takes place at a pressure of 0.0-1.0 bar and a temperature of 160-2500C, to obtain a melt of potassium formate. Water is added followed by filtration resulting in a solution having a content of >99% by weight of potassium formate, calculated on a water free basis.

    摘要: The present invention relates to a waterborne binder composition comprising a water dispersible polymer binder and a coalescing agent, which comprises triesters selected from the group consisting of tripropionin (triester of glycerol and propionic acid), tributyrin (triester of glycerol and butyric acid), tri-isobutyrin (triester of glycerol and isobutyric acid) or trivalerin (triester of glycerol and valeric acid) or combinations of two or more of these. The binder in the composition of the present invention is a homo- or copolymer comprising monomer units of acrylate, methacrylate, vinyl acetate and/or units of urethane or urethane/urea. In addition to the water dispersible polymer binder and the coalescing agent the composition may contain pigments, fillers and additives. The invention also covers the use of the binder composition in waterborne paint, adhesive or sealant.
