SOME ALDEHYDEAMINE ACCELERATORS.
Abstract
As part of the search for better accelerators for rubber vulcanization, a study is undertaken of some aldehydeamines with the purpose of correlating molecular structure with the physical properties imparted to the product. Six compounds synthesized for the study were evaluated in comparison with mercaptobenzothiazole (Captax) and the heptaldehydeaniline condensation product (Hepteen Base) with regard to tensile strength, tensile stress at 500% elongation, ultimate elongation, oven aging, oxygenbomb aging, compression set, free sulfur, and hardness. None possessed the oxygen-resistant property of Captax. In the presence of an antioxidant however, N,N' -dibenzylidene ethylene diamine compared favorably with standard accelerators. It was found to act efficiently alone, as well as in various combinations with one or more of the compounds, Captax, benzothiazyldisulfide (Altax), and zinc dimethyl dithiocarbamate (Methyl Zimate).
