    Abstract: 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.

    Abstract: 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.
