| 摘要 |
<p>The present invention relates to a method of incorporating dyes into polymeric materials. The method involves: a) providing a high molecular weight polymer precursor having polymerizable or cross-linkable groups; b) providing a functionalized dye having at least one polymerizable or cross-linkable group capable of reacting with the polymerizable or cross-linkable groups on the polymer precursor; c) mixing the high molecular weight polymer precursor with the functionalized dye to form a prepolymerization mixture; d) dispensing the prepolymerization mixture into a mold; and e) applying radiation to the prepolymerization mixture in the mold, thereby bonding dye to polymer precursor and cross-linking and/or polymerizing the polymer precursor to form a radiation-absorbing polymeric article. The method of the invention is particularly suitable for the manufacture of tinted contact lenses.</p> |
