Organosilicon compounds of the polyorganosiloxanes with ethylenically unsaturated by imide groups activated groups and method for their preparation

摘要

The invention concerns novel organosilicon compounds comprising a multifunctional polyorganosiloxane (POS) comprising, per molecule, and bound to silicon atoms, at least a hydroxyl radical and/or at least an alkoxyl radical and at least a group containing an activated double ethylene bond consisting in a maleimide group. The invention also concerns functionalizing methods resulting in said POS, in particular consisting in reacting an organosilane bearing a maleamic acid function and at least two alkoxyl functions with a polysilazane. Said compounds comprising a multifunctional POS are capable of exhibiting interesting properties, for example, as coupling agent (white filler-elastomer) in rubber compositions based on isoprene elastomer(s) comprising a white filler as reinforcing filler.
