Abstract: Disclosed herein is a a polymer composition (PC) including at least one thermoplastic polymer (A) and fibres (B) having a fibre length l. At most 10% by weight of the fibres (B), based on the total weight of the fibres (B), have a fibre length l of less than 100 μm, and at most 12% by weight of the fibres (B), based on the total weight of the fibres (B), have a fibre length l of less than 200 μm. Further disclosed herein are a process for producing the polymer composition (PC), a process for producing a moulded article by forming the polymer composition (PC) and a moulded article including the polymer composition (PC). Additionally disclosed herein is a method of using fibres (B) for increasing the toughness and/or reinforcement of moulded articles made from the polymer composition (PC).
