摘要:
A non-crystalline 1,1,3-tris(2-methyl-4-hydroxy-5-tert-butylphenyl)butane having an amorphous X-ray diffraction pattern and a melt transition temperature of 113-119°C is made by an improved process and offers improvements over crystalline materials as a stabiliser of polymeric materials such as polypropylene.
