Information on the efficiency of stabilisers in protecting polymers against thermal oxidation under service conditions is essential for selection and development of appropriate stabilizing systems. Accelerated tests are necessary to get data in an ac

Conjugated dimeric quinone methides (QM) arising by oxidation of phenolic antioxidants are considered principal stabilizer-born contributors to hydrocarbon-based polymer discoloration. After a prolonged exposure to a UVA-340 fluorescent lamp, the dis

Part of colour development in aged polyolefins stabilized with phenolic antioxidants can be attributed to the formation of conjugated diene compounds, arising as a consequence of sacrificial trapping of alkylperoxy radicals by phenolics. The discolor

The influence of a phenolic antioxidant and two hindered amine stabilizers (HAS) on the degradation behaviour of isotactic polypropylene was investigated for temperatures in the range 120–149°C. Consistent with earlier reports, phenolic-stabilized

For many years, sterically hindered phenols have been the standard for the long-term thermal stabilization of polyolefin pipes. Recently, an advanced stabilization system was developed which offers better gas and water extraction resistance than thes

For the plastic waste management the material recycling is of particular interest. However, it is important that the recyclate can compete with the virgin resins in higher value added applications. The remaining stabilizer residues in post consumer r
