Abstract:
There is provided a process for producing an organopolysiloxane A comprising at least one (meth)acrylate group, said process comprising the following steps: a) the following are reacted at a temperature of between 50 and 140° C., optionally between 70 and 130° C.:          at least one organopolysiloxane B comprising at least one epoxy group, with acrylic acid or methacrylic acid or a mixture of the two, in the presence of a catalyst C which is a complex of iron in the oxidation state (III), of formula (1) below:   [Fe(L 1 ) 3 ]  (1) in which the symbols L 1 , which may be identical or different, represent a ligand chosen from the group made up of: a β-dicarbonylato anion or the enolate anion of a β-dicarbonyl compound, a carboxylate anion and an alkoxide anion, and of at least one solvent, and b) the product obtained, which is said organopolysiloxane A or a mixture containing predominantly said organopolysiloxane A, is isolated.

Claim (Index 5):
The process as claimed in  claim 1 , wherein the organopolysiloxane B comprises siloxyl units (I.4) and (I.5) having the formulae below: Y a \ue89e Z b 1 \ue89e SiO 4 - ( a + b ) 2 \ue89e \ue89e and ( I \ue89e .4 ) Z c 2 \ue89e SiO 4 - c 2 ( I \ue89e .5 ) in which: a=1 or 2, b=0, 1 or 2 and a+b=1, 2 or 3, c=1, 2 or 3,\n the symbols Y, which may be identical or different, represent a hydrocarbon-based group comprising an epoxy group and optionally also comprising one or more heteroatoms optionally an oxygen atom, said hydrocarbon-based group Y optionally having from 2 to 20 carbon atoms inclusive, and optionally Y is chosen from the group made up of an alkyl glycidyl ether, a linear, branched or cyclic epoxy alkyl, a linear, branched or cyclic epoxy alkenyl and a carboxylic acid glycidyl ester; \n the symbols Z 1  and Z 2 , which may be identical or different, represent a monovalent hydrocarbon-based group having from 1 to 30 carbon atoms, optionally chosen from the group made up of alkyl groups having from 1 to 8 carbon atoms and aryl groups having from 6 to 12 carbon atoms, and optionally chosen from the group made up of a methyl, ethyl, propyl, 3,3,3-trifluoropropyl, xylyl, tolyl and phenyl group, and \n said organopolysiloxane B comprises, per molecule, at least two silicon atoms and at least one siloxyl unit (I.4).
