发明名称 Method and composition for incorporating radiation-absorbing agents into polymers
摘要 A method of incorporating radiation-absorbing agents (i.e., dyes) into polymeric materials. A preferred method involves crosslinking or polymerizing a polymerizable or crosslinkable material in the presence of a polymeric dye. A preferred product is a tinted contact lens comprising poly(vinyl alcohol). The methods offer advantages in reduced fabrication cycles, reduced extractables, elimination of post-polymerization activation steps, elimination of post-polymerization extraction steps and reduced scrap and costs associated with lens handling.
