Process for producing tyres, wherein crosslinkingnis carried out on a composition comprising: : (a) atnleast an elastomeric polymer containing carboxylicngroups; (b) at least a liquid organic compound containingnepoxide groups located internally on the molecule, andn(c) at least an oxide or an inorganic salt of a metalnselected from Fe, Cu, Sn, Mo and Ni. Upon heating, thenelastomeric material reaches a high degree ofncrosslinking without the addition of conventionalncrosslinking agents, with crosslinking times maintainednwithin limits which are acceptable for an industrial use.nThese compositions are particularly suitable fornproducing tread bands. |
