RUBBER COMPOUNDS CONTAINING SILICON DIOXIDE FOR THE PRODUCTION OF TYRES

摘要

A method for preparing a rubber compound comprising at least one first mixing step in which at least part of a cross- linkable polymer base is mixed at least with a reactive reinforcing filler, a dendrimer functionalized with polar groups adapted to interact with the reactive reinforcing filler and a nucleophile agent; and a subsequent mixing step in which the compound being prepared is mixed with a vulcanization system.
