2-Sulphobenzoic Acid Imide as a Rubber Mixing Ingredient

Abstract

A large number of scarce, often toxic, ingredients are currently being used in the tyre industry, and therefore it is urgent to create new, effective, readily available, and non-toxic rubber mix ingredients. N-Nitrosodiphenylamine, which is used as a scorch retarder [1, 2], is a toxic substance affecting the central nervous system and the activity of blood and liver enzymes; it is a potentially carcinogenic substance [3]. It causes colouring of rubber compounds and can break down during vulcanisation, which leads to the production of porous vulcanisates.
