The present invention is in the field of methods for determining material properties from foam samples. It relates to a computer-implemented method for determining a material property of a foam sample comprising (a) providing a representation of the sample, (b) extracting at least one structural feature from the representation, wherein the at least one structural feature comprises walls, struts, or nodes (c) providing the at least one structural feature to a material model suitable for obtaining at least one material property from the structural feature, and (d) outputting the at least one material property received from the material model.

Mixture for use in a fused filament fabrication process

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.

The present invention relates to the use of a polymer comprising polymerized units (A) and (B): (A) at least one first monomer of the formula (I) where n is 3 to 12; m is 0 to 3; Ris C-C-alkyl, C-C-alkenyl, aryl or aralkyl; R, Rand Rare each, independently of one another, hydrogen, C-C-alkyl, C-C-alkenyl, aryl or aralkyl; and (B) at least one second monomer of the formula (II) where R, Rand Rare each, independently of one another, hydrogen, C-C-alkyl, C-C-alkenyl, aryl or aralkyl; Ris C-C-alkyl, C-Calkenyl, aryl or aralkyl; as a support material in a fused filament fabrication process. 

Polymers as support material for use in fused filament fabrication

A process produces a polymer composition (A) containing a styrene copolymer (a) and an impact modifier (b), comprising a copolymer (b1) as graft base and a graft (b2), where the steps of the process are: (1) providing a crosslinked copolymer (b1) made of: (b11) from 70 to 99.99% by weight of a conjugated diene or acrylate, (b12) from 0 to 29% by weight of another comonomer, (b13) from 0 to 10% by weight of crosslinking monomers, and (b14) from 0.01 to 0.7% by weight of a chain-transfer reagent; (2) applying, to the copolymer (b1), at least one graft (b2) comprising: (b21) from 65 to 95% by weight of a vinylaromatic monomer, (b22) from 5 to 35% by weight of acrylonitrile and/or methacrylonitrile, and (b23) from 0 to 30% by weight of monoethylenically unsaturated monomers, thus providing the impact modifier (b); (3) mixing the styrene copolymer (a) and the impact modifier (b), and thus leads to improved mechanical properties of the polymer composition (A).

Process for producing thermoplastic polymer compositions with optimized degree of crosslinking

A composition for the immediate stopping of a free-radical polymerization comprises a) an inhibitor for the free-radical polymerization selected from among phenothiazines, b) an aprotic solvent and c) an ionic liquid. It serves to stabilize free-radically polymerizable monomers against free-radical polymerization. For the immediate stopping of free-radical polymerizations, the composition is added to a free-radically polymerizing system.

The present invention relates to a liquid composition comprising A) an organic active ingredient which is sparingly water-soluble and sparingly oil-soluble, in dissolved form, B) an oil which is soluble in water at 20&#xb0; C. to at most 20 g/l, and C) an ionic liquid comprising a cation and an anion as described below. Also provided is a process for the preparation of the liquid composition, where the active ingredient, the oil and the ionic liquid are brought into contact; and also the use of the ionic liquid for increasing the solubility of the active ingredient in an oil.
