<p>Oxide or silicate fillers modified with a mercapto silane (I) and an alkylsilane (II) and/or with a silicone oil are new. Oxide or silicate fillers modified with a mercapto silane of formula (R<1>)3Si-R<2>-SH (I) and an alkylsilane of formula (R<1>)3Si-R<3> (II) and/or with a silicone oil are new: R<1> = alkoxy or alkyl, at least one being alkoxy; R<2> = a divalent hydrocarbon group; R<3> = (un)saturated alkyl. Independent claims are included for: (1) a process for producing the modified fillers, comprising mixing an oxide or silicate filler with (I) and (II) and/or with a silicone oil; and (2) rubber mixtures comprising rubber, a modified filler as above, and optionally precipitated silica, carbon black and/or other rubber additives.</p> |
