| abstract | An acid salt (or such a mixture of the acid and base as to produce an acid salt) of ammonium or substituted ammonium including urea and thiourea, is included as an ingredient in a vulcanizable rubber mix. The salt decomposes with evolution of ammonia or amine at or near the vulcanization temperature. The acid itself, for example, malonic, may also decompose with partial or complete loss of acidity. Such an ingredient has a "delayed action" effect on vulcanization. The base may be ammonium, alkylammonium, polymethylene ammonium, urea, alkylurea, thiourea or alkylthiourea. Acids include citric, oxalic, tartaric, sebacic, adipic, sulphuric, phosphoric and malonic. The salt may be introduced in solution, or in admixture with clay or other inert powder. Two examples are given. In the first Provisional Specification, examples include the use of normal salts of decomposable acids, normal urea and thiourea malonates being given specifically, and the second Provisional Specification refers to the use of salts, particularly acid salts, of decomposable bases. Specifications 381,189 and 394,007 are referred to. |
