    摘要: The new amorphous modification of 1,1',1"-nitrilo{tri-2-propyl-tris-[2,2'-ethylidene-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.
