Neutralization by filler

摘要

The invention relates to a method for adjusting the pH value and/or for neutralizing acid and/or basic compounds, in particular degradation or decomposition products, as part of the reprocessing and recycling of in particular thermoplastic materials, in the course of which the polymer particles are permanently moved and heated in a reactor, wherein at least one filler is added for neutralization purposes, specifically in a quantity which corresponds at least to the anticipated acid or alkali load.
