Abstract:
A method of forming a radiation-absorbing polymeric article, comprising the steps of:a) providing a vinyl-functionalized polymer precursor having an average molecular weight of at least about 2000; and comprising polymerizable or crosslinkable groups;b) providing a vinyl-functionalized dye having at least one polymerizable or crosslinkable group capable of reacting with the polymerizable or crosslinkable groups on the polymer precursor;c) mixing the functionalized polymer precursor with the functionalized dye to form a prepolymerization mixture;d) dispensing the prepolymerization mixture into a mold; ande) applying radiation to the prepolymerization mixture in the mold, thereby bonding the dye to the polymer precursor through a saturated carbon--carbon bond; and crosslinking and/or polymerizing the polymer precursor to form a radiation-absorbing polymeric article.
