摘要： The invention describes powders for use in the production of spatial structures, i.e. molded bodies, using layer build-up methods, as well as methods for their efficient production. The powders have the special feature that they have good flow behavior, for one thing, and at the same time, have such a composition that the molded body that can be produced with the powder, using rapid prototyping, has significantly improved mechanical and/or thermal properties. According to a particularly advantageous embodiment, the powder has a first component that is present in the form of essentially spherical powder particles, which is formed by a matrix material, and at least one further component in the form of stiffening and/or reinforcing fibers, which are preferably embedded in the matrix material.

摘要： The invention relates to a method for the purification of poly(arylene ethers) of formula (I) in which m=0 to 1.0, n=1.0-m, and Ar1, Ar2, Ar3 and Ar4 independently represent divalent arylene groups. The compound of formula (I) is produced in a first step 1, with a raw product being obtained by bringing a metal or ammonium salt of divalent dihydroxy derivatives of Ar1 or Ar3 into contact with one or more dihalogenated derivatives of Ar2 and/or Ar4, in the presence of a solvent LM1. A precipitate that is present, if appropriate, is separated (step B) so as to obtain a solution L which then undergoes a membrane filtration (step C).
