Abstract: The present invention relates to a sinter powder (SP) comprising at least one semicrystalline terephthalate polyester (A) which is prepared by reacting at least one aromatic dicarboxylic acid (a) and at least two aliphatic diols (b1) and (b2), where the aliphatic diol (b1) is neopentyl glycol. The present invention further relates to a method of producing the sinter powder (SP), and to a method of producing a shaped body by sintering the sinter powder (SP). The present invention further relates to the shaped body obtainable by the sintering. The present invention also relates to the use of the sinter powder (SP) in a sintering method.

Abstract: 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, Ar1 and Ar2 are independently from each other C6-14-arylene or C6-14-aryl, which may be substituted with 1 to 4 substituents independently selected from the group consisting of C1-30-alkyl, C2-30-alkenyl, C2-30-alkynyl, C5-8-cycloalkyl, C6-14-aryl and 5 to 14 membered heteroaryl, and X1, X2 and X3 are 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.
