Abstract: The invention relates to a polymer powder comprising a copolymer, to the use of said powder in a shaping method and to moulded bodies that are produced from said polymer powder. The shaping methods are methods that operate layer by layer using a powder and during said methods areas of each layer are fused by the non-focussed application of electromagnetic energy. Selectivity can be achieved in a masking process, by the application of inhibitors, absorbers, or susceptors, without restricting the invention to the use of these substances. The inventive powder is preferably used in methods, in which selectivity is achieved by the application of inhibitors or susceptors or in a masking method. Once cooled, the solidified moulded bodies can be removed from the powder bed. The component characteristics of the moulded bodies that have been produced using the inventive powder according to the inventive method, in particular the mechanical and thermal component characteristics, can be varied within a wide range, depending on their composition, in comparison to moulded bodies produced from conventional powders. For amorphous copolymers in particular, the flow behaviour for the shaping method can be optimised by the skilful selection of comonomers. An additional advantage is that processing can also be simplified by the skilful composition of the copolymer. It is possible to conduct the processing at lower temperatures, which simplifies the temperature control and accelerates said processing. The slower crystallisation of semi-crystalline polymers in comparison to semi-crystalline homopolymers promotes the coalescence of the fused particles and leads to improved shrinkage behaviour in the moulded bodies.

Abstract: The present invention provides copolyester compositions and novel methods employing such compositions. The copolymer compositions comprise a copolyester containing a low polarity block in the copolyester backbone, thereby resulting in adhesive and coating materials that exhibit improved flow and wettability and superior initial adhesion and retained adhesion to various substrates.

Abstract: The application provides polymerization catalysts for the condensation of polyesters. The catalyst is in the form of a clear chlorine and/or bromine containing solution of a metal glycoxide and a metal glycolate having a pH in the range of from 0 to about 1, and containing chlorine and/or bromine atoms at a number ratio of chlorine and/or bromine to total metal cations in the catalyst ranging from about 0.5:1 to about 3:1. Polyesters produced with this catalyst have good melt elasticity, and good melt viscosity. The former property is desirable for the preparation of large and complex shaped polyester containers, and the latter property is desirable for melt spinning of industrial grade fibers and tire cords.

Abstract: A polyester resin for toner, which is composed of an acid component containing at least one member selected from the group consisting of aromatic dicarboxylic acids and lower alkyl esters thereof and an alcohol component containing at least one member selected from among bisphenol A derivative diols and wherein the content of aldehyde compounds, decomposition products thereof and by-products is 200 ppm or less. The resin does not emit any irritant odor in the step of preparing a toner, and the toner does not emit any irritant odor even when heated in copying work. Further, the toner gives well-defined images free from fogging due to a reduction in the transparency of a copy, has a wider range of reproduction of color tone, and is excellent in the image accuracy of a copy.
