Beschreibung
Zusammenfassung:	Additives such as colourants may be incorporated into polymeric materials such as polyesters , such as in polyester fibre production , by use of a liquid formulation comprising colourant and a vehicle. The vehicle may comprise a functionalised pentaerythritol , trimethylolpropane or trimellitate. The liquid formulation is suitably contacted with the polymeric material in a melt processing apparatus.
