A thermoplastic composition includes a poly(etherimide-siloxane) copolymer having a siloxane content of more than 0 to less than 50 weight percent based on the total weight of the poly(etherimide-siloxane) copolymer; an aromatic polyketone; and a mineral filler having a particle diameter of 0.1-2 micrometers. The thermoplastic composition has a lower toxicity index than the same composition without the aromatic polyketone, the mineral filler, or both, as determined in accordance with EN53505.

The present invention relates to polyketone moulding compounds based on partially crystalline, aliphatic polyketones. In particular, it relates to fibre-reinforced moulding compounds based on aliphatic polyketones which preferably comprise small quantities of phosphinic acid or the salts thereof. The moulding compounds are distinguished by improved mechanical properties and good processability in injection moulding. These moulding compounds are suitable for the production of in particular thin-walled moulded articles for the electrical and electronics industry, such as for example housings, housing components or connectors.

Disclosed is a polylactic acid composition with improved heat-resistance and improved impact-resistance. Specifically, in the disclosed polylactic acid composition, both impact strength and heat-resistance are improved by mixing 30 to 80 wt % of polyketone and 10 to 40 wt % of modified rubber. The disclosed polylactic acid composition does not only exhibit excellent in heat resistance, chemical resistance, fuel permeation resistance, abrasion resistance, etc., but also has improved impact-resistance and improved heat resistance. Thus, it is possible to employ polylactic acid as a bioplastic in interior/exterior parts of a vehicle.
摘要:
A thermoplastic composition based on polyamide and polyketone is described. The thermoplastic composition can have an excellent mechanical strength and dimensional stability. Further, the composition can include a novolac resin and a reinforcing or a bulking filler. The composition can be molded, for example in the form of granules or powder, which is used for manufacturing articles via an injection-molding process.
