ABSTRACT:
A branched chain polyalkylenepolyamine ("PAPA") amine having plural amine groups including a secondary amine group intermediate terminal primary amine groups and having at least two carbon atoms between each amine group, is reductively alkylated with a ketone to provide a PAPA alkylated only at an unhindered primary amine group. A preselected degree of steric hindrance at amine groups near each end of the chain enables cyclization by the `ketoform synthesis` by reaction with a ketone in such a manner as to form a polysubstituted piperazinone ("PSP") ring which includes N atoms of proximate primary and secondary amine groups of the alkylated PAPA. The PSP so formed may then be reacted with a reactive triazine ring so that a PSP substituent is linked to the triazine ring through a single N atom and at least two C atoms, to form a 2-oxo-piperazinyl-triazine ("PIP-T"). Oligomers of the PIP-T may be prepared. The PIP-T compounds are excellent stabilizers against ultraviolet (uv) light degradation in light-sensitive synthetic resinous materials.
