    摘要： The present invention relates to an antioxidant composition comprising (a) 0.01-0.5% by weight of sterically hindered phenolic compound, (b) 0.01-0.5% by weight of phosphorous compound, and (c) 0.01-1% by weight of sulphurcontaining compound. Said antioxidant composition reduces degradation of plastic materials during processing and end-use and thus, increases the long term thermal stability of those plastic materials. Moreover, this invention relates to methods for producing a final polymeric article with an increased long term thermal stability and stabilization against ageing by radical decomposition processes and polymeric intermediate materials as well as polymeric articles comprising the inventive antioxidant composition.

    摘要： The present invention relates to a polyolefin composition with good resistance to degradation caused by chlorine dioxide-containing water and at the same time showing low migration of the used additives and its decomposition products, especially phenols, out of the composition. The present invention is also directed to a pipe made of such a polyolefin composition. The present invention further relates to the use of the polyolefin composition for the production of a pipe and to the use of a combination of particular types of antioxidants for increasing the resistance of a polyolefin composition against degradation caused by contact with chlorine dioxide-containing water and for maintaining at the same time a low migration of the used additives and its decomposition products, especially phenols, out of the polyolefin composition.
