Abstract
A polymerizable composition includes at least one first monomer and at least one second monomer, wherein the at least one first monomer includes an isohexide bis(allyl carbonate) monomer, and wherein the at least one second monomer includes one or more ethylenic unsaturations. Another 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 an isohexide; diallyl carbonate; and at least one polyol. A polymerizate including the polymerizable composition and an optical article including the polymerizable composition are also provided.
