Composition of plastic material and process for treating plastic materials for forming said composition

Abstract

A plastic composition includes a plastic material with a halogen content less than or equal to 0.5% by mass with respect to the plastic material, oligomers derived from the plastic contained in the plastic material, halogenated salts, and hydrocarbon. A related process for producing a composition of plastic material includes the steps of forming a composition; bringing the composition at a temperature between 150° C. and 450° C., and keeping the composition obtained in the temperature range for a time between 10 seconds and 30 minutes to form a final composition. The inerting agent is added during the process in an amount such that the ratio between the sum of the moles of the alkali metals belonging to group IA and the sum of the moles of halogen contained in the plastic material is at most 20:1.
