Thiobis phenol-nickel (ii) alkanolamine complexes and use in polymers

Abstract

Abstract NICKEL COMPLEXES OF ALKANOLAMINES AND NICKEL (II) THIOBISPHENOLS ARE PROVIDED HAVING THE GENERAL FORMULA: (R-)(3-M)-N(-CH2-CH2-OH)M 1-((-)O-),2-((2-((-)O-),5-R''- PHENYL)-S-),4-R''-BENZENE NI(+2) WHEREIN R IS HYDROGEN; ALKYL CONTAINING FROM 1 TO ABOUT 18 CARBON ATOMS INCLUDING CYCLIC, ACYCLIC AND BRANCHED RADICALS AS WELL AS COMBINATIONS THEREOF; SUBSTITUTED ALKYL CONTAINING FORM 2 TO ABOUT 36 CARBON ATOMS INCLUDING CYANOALKYL, ALKOXYALKYL, CARBALKOXYALKYL, CARBAMOYLALKYL AND R2N ALKYL WHEREIN R IS AS DEFINED HEREIN; ARYL CONTAINING FROM ABOUT 6 TO ABOUT 7 TO ABOUT 12 ATOMS; ARALKYL CONTAINING FROM ABOUT 7 TO ABOUT 12 CARBON ATOMS, ESPECIALLY MONO AND BICYCLIC AR(LOWERALKYL); AND ALKENYL CONTAINING FORM ABOUT 2 TO ABOUT 18 CARBON ATOMS; R'' IS AN ALKYL GROUP CONTAINING FROM 1 TO ABOUT 18 CARBON ATOMS; AND M IS AN INTEGER FROM 1 TO 3. THESE COMPLEXES ARE USEFUL AS LIGHT STABILIZERS AND/ OR DYE RECEPTORS IN POLYMERIC COMPOSITIONS.
