Title: Studies on natural rubber-bound diphenylamine antioxidants
Authors: Rani, Joseph
Keywords: diphenylamine antioxidants
photochemical reaction
rubber vulcanizates
Issue Date: 3-Jul-1994
Publisher: Elsevier Science Limited
Abstract: Diphenylamine was chemically attached to depolymerised natural rubber by photochemical reaction. The rubber-bound diphenylamine was characterised by TLC, HNMR, IR and TGA. The efficiency and permanence of the bound diphenylamine was compared with conventional amine type antioxidant in natural rubber vulcanizates. The rubber-bound diphenylamine was found to be less volatile and less extractable compared to the conventional antioxidant. The vulcanizates showed improved ageing resistance in comparison to vulcanizates containing conventional antioxidant . Also, the presence of liquid rubber-bound diphenylamine reduces the amount of plasticiser required for compounding.
