Functionalised silane-based compounds, methods for producing them and their use in the area of rubber materials

Compounds essentially consisting of a functionalized organosilane of formula:

• 16
• in which:
• the symbols R1, which are identical or different, each represent a monovalent hydrocarbon group chosen from:
• a linear or branched alkyl radical having from 1 to 4 carbon atoms;
• a linear or branched alkoxyalkyl radical having from 2 to 6 carbon atoms;
• a cycloalkyl radical having from 5 to 8 carbon atoms;
• and a phenyl radical;
• the symbols R2, which are identical or different, each represent a monovalent hydrocarbon group chosen from:
• a linear or branched alkyl radical having from 1 to 6 carbon atoms;
• a cycloalkyl radical having from 5 to 8 carbon atoms;
• and a phenyl radical;
• Z is a functional group, comprising an activated ethylenic double bond, chosen from:
• a maleamic ester functional group Z2 of formula:
• 17
• and a fumaramic ester functional group Z3 of formula:
• 18
• in which formulae:
• R3 is a divalent, linear or branched, alkylene hydrocarbon radical having from 1 to 10 carbon atoms, possibly interrupted by at least one oxygen-substituted heteroatom whose free valence carried by a carbon atom is linked to the Si atom;
• the symbols R4, R5 and R6, which are identical to or different from one another, each represent a hydrogen atom or a monovalent hydrocarbon group chosen from:
• a linear or branched alkyl radical having from 1 to 6 carbon atoms;
• and a phenyl radical;
• R7 is a monovalent hydrocarbon group chosen from:
• a linear or branched alkyl radical having from 1 to 6 carbon atoms;
• and a phenyl radical;
• a is a number chosen from 1, 2 and 3.
