| 摘要 |
The field of the present invention is that of novel organosilicon compounds comprising a multifunctional polyorganosiloxane (abbreviated as POS) comprising, per molecule, and attached to silicon atoms, firstly at least one hydroxyl radical and/or at least one alkoxy radical, and secondly at least one group containing an activated ethylenic double bond consisting of a maleimide group. The present invention also relates to functionalization processes leading to the POSs targeted above, which consist in particular in reacting an organosilane bearing a maleamic acid function and at least two alkoxy functions with a polysilazane. The compounds comprising a multifunctional POS as targeted above are capable of showing advantageous properties, for example of acting as coupling agents (for white filler-elastomer coupling) in rubber compositions based on isoprene elastomer(s) comprising a white filler as reinforcing filler. |
