POLY-BIS-TRIAZINYLAMINES, A PROCESS FOR THEIR PREPARATION, THEIR USE FOR STABILIZING SYNTHETIC POLYMERS AND THE POLYMERS THUS STABILIZED

摘要

Hitherto unknown poly-bis-triazinylamines which have a linear structure, are not crosslinked and have a degree of polymerization of up to approx. 200, of the formula in which at least one of the radicals R1 to R5 must be a polyalkylpiperidyl group or must contain this group, are obtained by controlled reaction of a cyanuric hallde with diamines in several successive proccss stages. The new compounds can be used as sparingly volatile and particularly migration-resistant light stabilizers for synthetic polymers.
