In the alternative, they can be grafted by a method involving the action of ionizing radiation with simultaneous absorption of organosilane compounds and the action of radiation. The method is suitable for producing films, sheets, fibers, panels, coatings, pipes, hollow objects, foamed materials and molded articles.

The process according to the invention comprises hydrolyzing tetraalkoxysilane monomers in a hydrolysis step; and polymerising said hydrolyzed monomers in a polymerization step by subjecting them to conditions conducive to polymerisation to form an organosiloxane polymer. The hydrolysis step is conducted in a reaction medium comprising an organic compound with hydroxy groups. The invention allows for the synthesis of siloxane polymer compositions suitable for thin-film applications using a high content of tetra- and trifunctional silixane polymer precursors.

In doing so the vinyl silane is allowed to react with the polymer chain ends of the neodymium rubber to functionalize the chain ends of the polymer chains with silicon containing groups. This results in the rubber having better characteristics for utilization in tire rubber formulations, such a tire tread formulations, that exhibit improved wear characteristics and lower rolling resistance. The process for the synthesis of such functionalized polydiene rubber comprises (1) polymerizing a diene monomer in the presence of a lanthanide-based catalyst system, and (2) terminating the polymerization with a vinyl silane terminator. The functionalized polydiene rubber composition made by this method is comprised of a polydiene rubber which is functionalized at its chain ends with a silicon containing group.
