Abstract (en)

[origin: FR2759702A1] The disclosed polymerizable compositions comprise a monomer or a mixture of hydrophilic monomers, as well as a crosslinking agent comprised of an oligomer or a mixture of urethane oligomers having a mole weight of between 500 and 5,000 and two to six (meth)acrylate functions. The invention can be used in the manufacture of contact lenses.
