Abstract
A dyeable olefinic polymer composition comprising an olefinic polymer, and the reaction product of 50 to 90% by weight of the full nickel phenolate of o,o'-bis(p-1,1,3,3-tetramethylbutylphenol)sulfone and 50 to 10% by weight of a secondary or tertiary organic phosphite.
Claims14
A dyeable olefinic polymer composition comprising an olefinic polymer, about 0.7 to 4% by weight of the reaction product of about 50 to 90% by weight of the full nickel phenolate of o,o'-bis(p-1,1,3,3-tetramethylbutylphenol)sulfone, and about 50 to 10% by weight of a secondary or tertiary organic phosphite.
A method of dyeing an olefinic polymer composition comprising:
- (a) incorporating into an olefinic polymer about 0.7 to 4% by weight of the reaction product of about 50 to 90% by weight of the full nickel phenolate of o,o'-bis(p-1,1,3,3-tetramethylbutylphenol)sulfone and about 50 to 10% by weight of a secondary or tertiary organic phosphite,
- (b) forming a fiber or film therefrom, and
- (c) contacting said fiber on film with a chelatable dye.
