Deterioration due to heat of PP, which is discussed in this paper, especially when it is deteriorated by accelerated deterioration test, is affected by the structure of PP itself, but it is greatly affected by additives such as antioxidants and Many, the internal cause is mainly the type and concentration of the antioxidant, and the external cause is heat. However, when analyzing the deterioration of market-recovered products, it is necessary to consider various possibilities including the internal cause because the external cause is not clear. In addition, since the case where durability depends on antioxidants often applies to other polymers, the author like to consider this PP as one subject.
Seikei Kako published new progress about 31570-04-4. 31570-04-4 belongs to esters-buliding-blocks, auxiliary class Mono-phosphine Ligands, name is Tris(2,4-di-tert-butylphenyl) phosphite, and the molecular formula is C42H63O3P, SDS of cas: 31570-04-4.
