## (57) ABSTRACT 

The present invention relates to polyketone moulding com› pounds based on partially crystalline, aliphatic polyketones. In particular, it relates to fibre-reinforced moulding com› pounds 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.
