DECOMPOSING POLYMERS USING NOR-HALS COMPOUNDS

摘要

A method is described for the decomposition of polymers, especially was te plastics and used plastics, in which so-called NOR-HALS compounds - that is, for example, compounds comprising the group See formula I in which R* is C1-C20alkyl, OH-substituted C1-C20alkyl, optionally C1-C4alkyl- substituted C5-C12cycloalkyl or O- or S-interrupted C2-C20alkyl - are added and heating is carried out at temperatures which lie above the customary processing temperatures fo r polymers (280.degree.C or more).
