Crosslinked, hydrophobic acrylic copolymer made of 2-phenoxytetraethylene-glycol acrylate and intended for intraocular lenses

Abstract

The material according to the invention is a hydrophobic, cross-linked, acrylic copolymer of at least the following monomers: an arylalkoxy-acrylate different from a 2-phenoxy-(2-ethoxy)n-acrylate with 4≦n≦6; a 2-phenoxy-(2-ethoxy)n-acrylate with 4≦n≦6, preferably 2-phenoxy-tetraethylene-glycol acrylate; a hydroxylated acrylate; a hydroxylated methacrylate; an ethoxylated diol diacrylate; and an ethoxylated diol dimethacrylate. It is obtained in one single step of radical polymerization, in the presence of a transfer agent during the cross-linking. It thus has a physical structure corresponding to a three-dimensional macromolecular network with hanging chains. This material is used for manufacturing intraocular lenses (1) with low glistening that are not self-adhering.
