Uv-absorbing benzotrizaoles having a styrene group |
| 摘要 |
A reactive monomer for preparing ultraviolet absorbing polymers has formula (I) wherein R1 is a halogen or C1-C6 straight or branched chain alkoxy group; and R is a -(CH2)3O-, -(CH2)2O-, -CH(CH3)CH2O-, -CH2CH(CH3)O(-, -(CH2)3OCH2-, -(CH2)2OCH2-, -CH(CH3)CH2OCH2-, or -CH2CH(CH3)OCH2-group. The compound can be used to produce ultraviolet absorbing polymers, such as those used for ocular devices including contact and intraocular lenses. |
