Macromolecules include polymers bound or bound directly to multiatomic functional groups. The multiatomic functional group may be located at the end of the polymer and may be formed simultaneously with or immediately after the formation of the polymer. The macromolecules are hydrolyzed and condensed in the presence of excess compounds containing Si, Ti, Zr, Sn, Al, or Fe atoms in which at least one alkoxy group is bonded to a silicon atom (e.g., By the gel process). Such macromolecules may be used alone or in combination with other polymers and / or other particulate fillers in the manufacture of vulcanizates and tire components. |
