Studies on antioxidants, 1. Phenolic antioxidants as stabilizers for polypropylene

Abstract: A group of phenolic antioxidants was synthesized, characterized and the performance of these antioxidants in polymer processing was tested in the polymer melt by multiple extrusions. The change in melt flow was observed and compared with the change in melt flow by use of commercially available antioxidants. All the antioxidants examined had the same phenolic stabilization moiety but varied in the size of the substituents in the para-position of the aromatic ring. Increasing length of the side chain considerabl… Show more

“…In our earlier studies,6–9 we modified the structure of BHT by introducing a bulky group at a para position to the OH group. Novel antioxidants, based on hindered phenol in combination with acid hydrazides and thiosemicarbazones, were synthesized.…”
