Abstract
A tire comprises >=1 structural element including a crosslinked elastomeric material obtained by crosslinking a crosslinkable elastomeric compn. comprising (a) 100 phr of >=1 diene elastomeric polymer, (b) 5-120 phr, preferably 10-80 phr, more preferably 20-50 phr, of >=1 layered material modified with >=1 alkyl ammonium or alkyl phosphonium salt, said layered material having an individual layer thickness 0.01-30 nm, preferably 0.05-15 nm, more preferably 0.1-2 nm, (c) 0.05-2 phr, preferably 0.1-1 phr, more preferably 0.2-0.5 phr, of >=1 N-acyl-sulfenyl amide, (d) 0.3-5 phr, preferably 0.5-4 phr, of >=1 org. or inorg. acid or a deriv. thereof selected from carboxylic acids, phosphoric acids, sulfonic acids, boric acids, or derivsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
