Abstract
(EN)
A method of preparing a polymer bound stabilizer comprises reacting a stabilizer precursor molecule containing a reactive double bond which is not readily homopolymerizable with a preformed polymer in the presence of a free radical. The stabilizer precursor may be, for example, a hindered piperidine, a hindered phenol antioxidant or a hindered arylamine antioxidant and the polymer may be a polyolefin, polystyrene, polyvinyl chloride, polyamide or an acrylonitrile butadiene styrene polymer, for example.
(FR)
Procédé de préparation d'un stabilisateur lié à un polymère consistant à faire réagir une molécule précurseur de stabilisateur contenant une double liaison réactive qui n'est pas facilement homopolymérisable avec un polymère préformé en présence d'un radical libre. Le précurseur du stabilisateur peut par exemple être une pipéridine retardée, un antioxydant phénolique retardé ou un antioxydant arylaminique retardé, et le polymère une polyoléfine, le polystyrène, le chlorure de polyvinyle, un polyamide ou un polymère acrylnitrile-styrène-butadiène, par exemple.
