Acrylic polymer material, hydrophobic for intraocular lens, of improved flexibility by the use of a transfer agent Acrylic polymer material, hydrophobic for intraocular lens, of improved flexibility by the use of a transfer agent
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.Material polímero acrílico, hidrófobo y reticulado, de deformabilidad incrementada, destinado a la realización de implantes oftalmológicos y más particularmente de lentes intraoculares, material que se presenta en forma de red macromolecular tridimensional obtenido por polimerización radicalaria a partir de una mezcla de monómeros acrílicos o de una mezcla de monómeros acrílicos y metacrílicos, caracterizado por el hecho de que la mezcla contiene: - compuestos reticulantes que actúan durante la polimerización para formar la red tridimensional； y además - al menos un agente de transferencia que interrumpe localmente la formación de esta red tridimensional durante la polimerización para crear cadenas colgantes.
