发明名称 POLYMERIZATION OF POLYOL (ALLYL CARBONATE) USING POLYMERIZATION INITIATORS OF SHORT AND LONG HALF LIVES
摘要 A liquid composition comprising a polyol(allyl carbonate), a photochromic agent, and a first peroxide polymerization initiator characterized in that a second peroxide polymerization initiator is present, the second initiator having a half life at least five times greater than the first, measured at the same temperature, in polyol(allyl carbonate) and a method of polymerizing a polyol(allyl carbonate) having a photochromic agent incorporated therein by adding a first peroxide polymerization initiator to the polyol(allyl carbonate) monomer and curing the polyol(allyl carbonate), characterised in that a second peroxide polymerization initiator is added to the polyol(allyl carbonate), the second initiator having a half life at least five times greater than the first, measured at the same temperature, in polyol(allyl carbonate).
