[0153] In order to demonstrate the unexpectedly found properties and the resulting possibilities for painting articles based on the compositions according to the invention, suitable polyester molding materials were initially produced by kneading. For this, the individual components were combined in a twin-screw extruder (ZSK 32 Mega mixer from Coperion Werner & Pfleiderer (Stuttgart, Germany)) at Mix and extrude at a temperature in the range of 260°C to 300°C, cool until pelletizable, and pelletize. After drying (approximately 2 h at 120° C. in a vacuum oven) the pellets were processed to form test samples.

[0154] The test samples reported in Table 1 for the study were injection molded on an injection molding machine at a melting temperature of 260°C and a mold temperature of 80°C.

Abstract

The invention relates to compositions, molding materials producible from the compositions, and to articles of manufacture in turn based on the molding materials, wherein the compositions comprise polyalkylene terephthalate or polyalkylene furanoate, at least one filler or reinforcer, and at least one secondary alkanesulfonate having two alkyl radicals.

Description

technical field [0001] The present invention relates to compositions comprising polyalkylene terephthalates or polyalkylene furanoates, at least one filler or A reinforcing agent and at least one secondary alkyl sulfonate having two alkyl groups. Background technique [0002] In Kunststoffe, Eigenschaften und Anwendungen, H.Domininghaus et al., 2008, Chapter 2.2 Synthetic Plastics (Synthetische Kunststoffe), Polycondensates (Polykondensate), p. 874, 2008, Springer (ISBN 978-3-540-72400-1) discloses that the painting of polybutylene terephthalate (PBT) based articles can be achieved with various paint systems such as Hydro-Soft paint. The automotive industry also knows primer and paint systems that allow in-line painting of PBT up to 160°C. According to Standothek, Kunststoffe und ihre Lackierung, Product brochure from Standox, Wuppertal, D12185782 D1007 5500, many problems can arise during the painting process, which in turn depend on a large number of parameters. By way ...
