Abstract:
The object of the invention is polymer compositions comprising cross-linked polymer comprising boronic ester functions enabling exchange reactions, as well as free monofunctional boronic esters. The compositions are obtained from the modification of a polymer by a functionalised boronic ester additive. This polymer can be pre-functionalised boronic ester or functionalised on addition of the said additive. In particular, the invention relates to a process enabling the behaviour of a polymer to be modified by addition of a functional additive, enabling a cross-linked network containing exchangeable boronic ester links to be formed.

Claim (Index 1):
Combinations to cross-link linear or branched polymers, said combinations being chosen from among the combinations comprising:\n A+B; A+C; A+B+C; B+C; A+compound of formula (Ia); or B+compound of formula (Ib1) or (Ib2); A, B and C corresponding to the following formulas: wherein G 1 , G 2 , G 3  and G 4  each represent, independently from one another, a functional group enabling the covalent binding of the molecules to the polymer chain to be functionalised; Rx, R\u2033x, and Ry, R\u2032y, R\u2033y are hydrocarbon groups; R\u2032v, R\u2032w and R\u2032x, identical or different, each represent a hydrogen atom, a hydrocarbon radical, or form together, as a pair, an aliphatic or aromatic ring; Rv and Rw, respectively R\u2033v and R\u2033w, identical or different, represent a hydrogen atom or a hydrocarbon radical or form an aliphatic or aromatic ring together, or with Rx, respectively or with R\u2033x; Ry, R\u2032y, R\u2033y are linked to the boron through a carbon atom, compounds of formula (Ia) and (Ib) corresponding to the following formulas: wherein n is a whole number between 1 and 6; i is a whole number between 1 and n; k equals 0 or 1; each ki equals 0 or 1; R 1 , R\u2032 1 , R\u2033 1 , R 3i , R\u2033 3i , R 5 , R\u2033 5 , R 7i , R\u2033 7i , identically or differently, each represent, independently from one another, a hydrogen atom or a hydrocarbon group; R 6 , each R 8i  identical or different, each represent a hydrocarbon group; {R 1 , R\u2032 1 , R\u2033 1 } can together form, in pairs, an aliphatic or aromatic ring; {R 3i , R\u2032 3i , R\u2033 3i } can together form, in pairs, an aliphatic or aromatic ring; {R 5 , R\u2033 5 } can together form an aliphatic or aromatic ring; {R 7i , R\u2033 7i } can together form an aliphatic or aromatic ring; R 2  and R 4 , identical or different, each represent a hydrocarbon group; R 2 , is linked to the boron atom by a covalent bond through a carbon atom; R 6 , each R 8i  is linked to the boron atom by a covalent bond through a carbon atom.
