Abstract
Nylon 66 polymer is stabilized against heat and light during its preparation by conducting the polymerization in the presence of certain copper complexes, such as cupric amminohydroxide, and KBr and/or KI. Less metallic copper is formed during polymerization than if copper salts (e.g. copper acetate) are used instead of the copper complexes.
