Cationic end-capped siloxane prepolymer for reduced cross-link density |
摘要 |
The present invention relates to hydrophilic dicationic siloxane prepolymers with one polymerizable vinyl moiety instead of two polymerizable vinyl moieties, resulting in contact lenses and/or biomedical devices with reduced cross-link density and modulus without detracting from other properties.
