A process for the preparation of a propylene polymer containing a coloring agent, including the steps of:

(i) forming a solid mixture (a-b)of (a) a ZN catalyst component made from or containing Mg, Ti, halogen and an internal electron donor compound, and (b) a coloring agent made from or containing at least a pigment; wherein the mixture being in a weight ratio (b):(a) ranging from 0.01:1 to 0.4:1; and

(ii) feeding the mixture (a-b) to a polymerization reactor and operating the reactor under polymerization conditions to produce the propylene polymer.

wherein the process having the b:a weight ratio and a time in days elapsed between mixture formation and use in polymerization fall below the curve defined by the equation y=3+0.832x.sup.−1,17 wherein y is the time in days elapsed between mixture formation and use in polymerization and x is the (b):(a) weight ratio.
