摘要: Description of a method for the production pigmented thermoplastic material. The characterizes that during first step an aqueous suspension presenting solid matter contents approximately 10 to 75% by weight, containing at least one flow enhancer in form dissolved salt and pigment, is ground under alkaline conditions high energy charging mill means grinding bodies having diameter 0.2 2 mm, obtained product transformed second with material into flush process performed kneader or extruder, increased temperature pH value initially 7 less. In addition, invention concerns produced according said method, as well beneficial applications transparent molded bodies, particular fibers, foils, injection moldings extruded parts. invention-specific provides plastic which can reliably be processed quality products. Foils are accordingly are, example, free from coloration defects.
