    摘要： The present invention refers to a hybrid photopolymer composition for additive manufacturing, comprising 50-95% by weight of a free radically curable-component, farther comprising at least one (meth)acrylate monomer or oligomer, 5-49% by weight of a cationically curable component, further comprising a cycloaliphatic epoxide, an oxetane mixture, containing a monooxetane compound and a polyoxetane compound, and a thermoplastic polycaprolactone with a molecular weight of 20,000-100,000 g/mol, a free radical photoinitiator, a UV blocker, a cationic photoinitiator, optionally a cationic photosensitiser, and optionally a thermal initiator, wherein the percent by weight is based on the total weight of the photopolymer' composition. The invention also relates to the use of a photopolymer composition according to the present invention for producing a three-dimensional object through additive manufacturing and to a three-dimensional object obtained through additive manufacturing using the photopolymer composition—according the present invention.

    摘要： The present invention refers to a method for producing a low-emitting plasticised polyvinylchloride composition, having a fusion time of less than 5.50 s and a volatility of less than 10% weight loss, by mixing pentaerythritol tetravalerate with a polyvinylchloride composition, the fusion time being measured according to DIN 54 802 and ISO/DIS 4574 and the volatility being measured according to ISO 176 Method A. In a further aspect the present invention refers to a thermoplastic article suitable for use in environments where the article is exposed to heat, wherein the thermoplastic article is based on a plasticized polyvinylchloride composition produced by the method of the present invention.

    摘要： The present invention refers to the use of an epoxide in order to reduce the formation of heavy ends in a continuous hydroformylation process, where an olefin or olefin mixture is reacted with carbon monoxide and hydrogen in the presence of a rhodium complex catalyst, comprising at least one organobisphosphite ligand, in order to produce an aldehyde. Said epoxide is added to the reaction mixture in an amount of 0.01-1.5 wt %, reducing the formation of heavy ends by 10-80%.
