Abstract
A polymerizable composition includes the reaction product of an isohexide bischloroformate, at least one polyol, allyl alcohol, and, optionally, at least one polychloroformate. An exemplary polymerizable composition includes the transesterification reaction product of (a) an isohexide, diallyl carbonate, and at least one polyol; and (b) organic peroxide. A polymerizate including the polymerizable composition and an optical article including the polymerizable composition are also provided.
