Amorphous modification of 1,1',1'-nitrilo(triethyl-tris-2,2'- methylene- bis(4,6-di-tert-butylphenyl) phosphite)

摘要

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.
