Abstract: Nickel organic compositions prepared from a nickel salt of a 1,3-diketone of the formula ##STR1## wherein R and R' are independently C.sub.1 -C.sub.8 alkyl; and sulfonyl dialkylphenols of the formula ##STR2## wherein R" and R'" are independently C.sub.1 -C.sub.12 alkyl are used to provide polymer compositions which have improved dyeability after exposure to high temperatures. Preferably, the nickel salt of acetyl-acetone and 2,2'-sulfonylbis-(4-t-octylphenol) are reacted together and the polymer is a polyolefin. Most preferably, the polyolefin is polypropylene.
