Abstract:
1. Process for preparing a granulate suitable for being supplied to an installation for melt-shaping a polymer composition comprising a matrix polymer and at least three additives, said process comprising the steps of: (i) mixing at least four different granule fractions, at least one granule fraction of the four granule fractions consisting of the matrix polymer and, optionally, one or more additives that are present in all granule fractions, and at least three other granule fractions of the four granule fractions comprising the matrix polymer and a different additive in a concentration that is between 1.5 and 30 times larger than the concentration of the different additive in the final composition, wherein a combination of colorants is regarded as a single additive, and (ii) collecting a mixture of the at least four different granule fractions from step (i) in a storage device.
