摘要:
A particular branched chain polyalkylenepolyamine ("PAPA") having plural amine groups including a secondary amine group intermediate terminal free primary amine groups (that is, neither one is hindered), and having at least two C atoms between each group, may be selectively cyclized with a ketoform reaction to form a polysubstituted piperazinone ("PSP"), with specific directivity. Such PSPs are linked to a triazine nucleus to yield piperazinone-triazine ("PIP-T") compounds which are excellent stabilizers for polyolefins and other light-degradable polymers. Certain acyclic polyalkylenepolyamines may have a PIP-T substituent at each N atom forming pendant PIP-Ts ("P[PIP-T]" for brevity) which are also excellent stabilizers, and like some of the PIP-Ts, some P[PIP-T]s provide photostabilization without noticeably interfering with the color of films and fibers provided by even pastel-colored pigments and dyes.
