Abstract
Process for the vulcanization of synthetic elastomers, in conjunction with vulcanizing agents and traditional additives (such as zinc oxide, stearic acid, filler fillers, carbon black, plasticizers, stabilizers, etc.) characterized by: A) the mixture of said synthetic elastomers is partially subjected to temperatures and/or times shorter than those necessary for complete vulcanization, whereby partially crosslinked products having an elongation at break of 300 to 2000% and preferably 500 to 1200% and a residual elongation less than 70% of its elongation at break, and B) to stretch the products obtained in a), with a stretch ratio corresponding to a percentage elongation lower than 10%, at least, to the elongation at break, at the same time that the vulcanization is completed at the same or different temperature from phase a), the elongation characteristics in phase a) being measured at the temperature at which the vulcanization is completed.
