    摘要： Crystalline modification of mixtures comprising (a) a nickel-quencher corresponding to [2,2′-thio-bis(4-t-octylphenolate)-n-butylamine Nickel (II)] and (b) a 2-hydroxy-4-alkyloxybenzophenone corresponding to 2-hydroxy-4-n-octyloxybenzophenone wherein it has two diffraction lines at angles 2{acute over (ø)}=6.291 and 2{acute over (ø)}=6.888 in the X-Ray diffraction spectrum from powders. The said crystalline modification can be used as a light stabilizer for agricultural films based on polyolefins or polyolefinic copolymers.
