Triacylated amidoxime derivatives, synthesis thereof and industrial applications thereof especially as crosslinking agents for polyolefins

摘要

New triacylated amidoxime derivatives, synthesis thereof and industrial applications thereof, especially as crosslinking agents for polyolefins, in particular of high density polyethylene, are described. These compounds correspond to the general formula: IMAGE in which R and R1 are monovalent organic radicals, and R2 and R3 are also monovalent organic radicals or form, with each other, an aliphatic, alicyclic or aromatic divalent radical -Z-. They can be prepared by a process which comprises the halogenation of an aldoxime in the hydroxamoyl halide form, which is then acylated and then reacted with an alkaline imide.
