Abstract
Improvements in the object of the main patent No. 279,550 by "Process for preparing vulcanized products", which show high mechanical characteristics, based on mixtures consisting of saturated and amorphous copolymers of ethylene with alpha-olefins (in particular, of ethylene with propylene or butene-1), of a reinforcing filler and of vulcanizing agents and containing or not filler acid-correction compounds, characterized by homogenously mixing the copolymer, a white mineral filler, the agent, if any, acidity corrector of the filler and a dispersion promoter, which consists of diallyl maleate; for the mixture to be subjected, if desired, to a thermomechanical treatment, in which case the mixture is then cooled, then the vulcanizing agents based on an organic peroxide and sulfur are added and finally the complete mixture is vulcanised at temperatures between 110º C and 220º C (preferably between 140º C and 180º C).
