POLYAMIDES STABILIZED WITH A PHOSPHINE

摘要

Synthetic linear polyamides which are stabilized against the degradative effect of heat by the incorporation therein of phosphine or of certain primary or secondary organophosphines, optionally together with a substituted phenolic or substituted diphenylamine antioxidant. These phosphines have a reduced adverse effect on the dispersion properties of titanium dioxide when used as a pigment in polyamides, compared with other phosphorus-containing stabilizers.
