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.
