Abstract

Fremgangsmåte for løsningsmid- del f ri gjenvinning av et anvendelig, stabilisert, termoplastisk materiale fra en blanding av minst en halogenert polymer og minst en ikke- halogenert termoplastisk polymer, hvor den halogenerte polymer underkastes en kontrollert termisk nedbrytning mens den ikke-halogenerte termoplastiske polymer ikke nedbrytes vesentlig, for å fremstille et resul- terende, stabilisert, termoplastisk materiale. Polymerblandingene formes til et håndterbart materiale, blandes med minst ett metalloksid som vil gi et halogenert metallsalt som er sta- bilt under de betingelser som kreves for å bearbeide og anvende det resul- terende termoplastiske materiale, i en mengde som minst er lik den stø- kiometriske mengde som kreves for é omsette alt halogen i blandingen, og polymerblandingene og metalloksidet underkastes forhøyet temperatur slik at polymerblandingen smelter og de halogenholdige polymerer nedbrytes termisk og utvikler halogensyregass som reagerer med metalloksidet, ut- viklet vann fjernes, og det resulter- ende, stabiliserte, termoplastiske polymermateriale samles. Det beskriv- es også anvendelse av metallsalt av alifatisk karboksylsyre i stedet for metalloksid, og i kombinasjon med dette.Solvent process for recovering a usable, stabilized, thermoplastic material from a mixture of at least one halogenated polymer and at least one non-halogenated thermoplastic polymer, wherein the halogenated polymer undergoes a controlled thermal decomposition while the non-halogenated thermoplastic polymer does not is degraded substantially, to produce a resultant, stabilized, thermoplastic material. The polymer blends are molded into a manageable material, blended with at least one metal oxide which will provide a halogenated metal salt which is stable under the conditions required to process and use the resulting thermoplastic material, at the kiometric amount required to react all the halogen in the mixture, and the polymer blends and metal oxide are subjected to elevated temperature so that the polymer blend melts and the halogen-containing polymers are thermally decomposed and develop halogen acid gas which reacts with the metal oxide, developed water is removed, and the resulting, stabilized , thermoplastic polymer material is collected. Also described is the use of metal salt of aliphatic carboxylic acid in place of metal oxide, and in combination with this.
