The invention relates to organophosphorous compounds having a polysulfide bridge, the method for the production and use thereof in the form of a crosslinking agent between mineral or metallic filler and elastomer. Said compounds correspond to a formula (I) (RO) 2-t R<1>t P (O)- Ox (CH2) y-Sz- (CH2 ) y-Ox-P (O) (OR) 2-t R<1>t, therein R is hydrogen, alkyl, aryl, trialkylsilyl, trialkylamino or an alkaline metal; R<1 >is alkyl or aryl; x is 0 or 1; y is an integer number ranging from 1 to 22, preferably from 2 to 4; z is 0 or 1. |
