<p>The incorporation of additives into thermoplastic polymers, in particular to give foamable polymers, which are used for the preparation of an extrudable melt is carried out without the use of an adhesion promoter by adsorbing the additives onto foam flakes, optionally mixed with polymer granules, and adding them in this form to the thermoplastics before the melting. The uniform distribution of the additives enables the preparation of end products having a smooth surface without bubbles or holes. Blockage of the extruder due to precipitated additives is also prevented.</p> |
