ABSTRACT:
The new amorphous modification of 1,1',1"-nitrilo{triethyl-tris-[2,2'-methylene-bis(4,6-di-tert-butylphenyl) ]phosphite} is obtained by cooling rapidly said compound from the melt to ambient temperature. This amorphous form is an effective process stabilizer for polyolefins, particularly polypropylene.
