<p>A method for producing polymer granules in specific colours and with specific abilities in a new manner without affecting the molecular structure of the polymer material in question, where a lacquer or glue containing colorants and/or additives are being prepared by using a soluble polymer material, where said lacquer is applied to the surfaces of the granular polymer material and where said material is dried until a surface film or coating of said colorants and/or additives has being attained. By proper controlling the amount of colorants and/or additives in accordance with the present amount of polymer granules it may hereby be achieved that every single granule is covered with the needed colorant and/or additive in order to obtain the predetermined properties of the polymer granules in question. Finally said colorants and additives are fixed to the surfaces of the polymer granules by drying or evaporation of the soluble agent.</p> |
