The present invention relates to the use of a filament comprising a core material (CM) comprising a ceramic material precursor (CMP) and the core material (CM) is coated with a layer of shell material (SM) comprising a thermoplastic polymer as a support material in a fused filament fabrication process. Further, the invention relates to three-dimensional objects and a process for the preparation thereof.

Filaments for use as a support material in fused deposition modeling

The present invention provides compositions comprising a) at least one polymer consisting of one polymerblock A and at least two polymerblocks B, wherein each polymerblock B is attached to the polymerblock A, and wherein at least 60 mol % of the monomer units of polymerblock B are selected from the group consisting of Formulae (1A), (1B), (1C), (1D), (1E), (1F) and 1G, 1H and 1I wherein R, R, R, R, R, R, Rand Rare independently and at each occurrence H or C-alkyl, and b) at least one crosslinking agent carrying at least two azide groups, as well as to layers formed from these compositions, electronic devices comprising these layers and to specific polymers encompassed by the polymers of the composition. 

Star-shaped and triblock polymers with enhanced crosslinkability

Polymers comprising at least one unit of formula (1) wherein n is 0 or 1, m and p are independently from each other 0, 1, 2, 3, 4, 5 or 6, provided that the sum of n, m and p is at least 2, and n and p are not 0 at the same time, Arand Arare independently from each other C-arylene or C-aryl, which may be substituted with 1 to 4 substituents independently selected from the group consisting of C-alkyl, C-alkenyl, C-alkynyl, C-cycloalkyl, C-aryl and 5 to 14 membered heteroaryl, and X, Xand Xare independently from each other and at each occurrence O or S, compositions comprising these polymers, and electronic devices comprising a layer formed from the compositions. Preferably, the electronic device is an organic field effect transistor and the layer is the dielectric layer. 

Ether-based polymers as photo-crosslinkable dielectrics

The invention relates to a process for producing molding compositions containing: a) from 55 to 85% by weight of copolymer A composed of vinylaromatic monomer A1 and a,B-unsaturated monomer A2; b) from 15 to 45% by weight of graft copolymer B with particle size from 50 to 550 nm composed of: B1: from 60 to 80% by weight of rubbery graft base B1 composed of: B11: from 80 to 99% by weight of at least one C2-C8-alkyl acrylate, B12: from 0.5 to 2.5% by weight of cyclic crosslinking agent, B13: from 0 to 2% by weight of non-cyclic crosslinking agent, B2: from 20 to 40% by weight of at least one graft shell B2 composed of: B21: from 60 to 75% by weight of a styrene, B22: from 25 to 40% by weight of acrylonitrile, c) from 0 to 10% by weight of additives C; where the reaction time of the polymerization for producing the graft base B1 is in the range from 2 to 5 h, and the addition of the starting materials takes place over at least two chronological segments.
