Abstract

The paper presents experimental results concerning optical and surface properties of a series of acrylic copolymers obtained by free-radical mass copolymerization. This study is part of a research project on polymeric biomaterials with potential use for new crystalline lens implants which could restore visual accommodation. The following monomers were used to obtain acrylic copolymers: metyl metacrylate, cyclohexyl metacrylate, 2ethyl hexyl acrylate, butyl acrylate. The wettability of these copolymers was investigated through measurements of static contact angle with water. Their refractive indices were determined by UV-visible spectroscopic ellipsometry..

Keywords
