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.
