摘要

Acrylic polymer material, hydrophobic and crosslinked, of increased deformability, intended for the realization of ophthalmological implants and more particularly intraocular lenses, material that is presented in the form of a three-dimensional macromolecular network obtained by radical polymerization from a mixture of acrylic monomers or a mixture of acrylic and methacrylic monomers, characterized in that the mixture contains: - crosslinking compounds that act during polymerization to form the three-dimensional network; and in addition - at least one transfer agent that locally disrupts the formation of this three-dimensional network during polymerization to create pendant chains.
