Title: | Studies on natural rubber-bound diphenylamine antioxidants |
Authors: | Rani, Joseph |
Keywords: | diphenylamine antioxidants plasticiser photochemical reaction TLC HNMR TGA IR rubber vulcanizates |

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. |
