Abstract
Official abstract text for this publication.
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 (a) the transesterification reaction product of 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polymerizable composition, comprising the reaction product of: an isohexide bischloroformate; at least one polyol comprising a linear or branched polyol; allyl alcohol; and optionally, at least one polychloroformate. 2. The polymerizable composition of claim 1 , wherein the isohexide bischloroformate is selected from the group consisting of isosorbide bischloroformate, isoidide bischloroformate, isomannide bischloroformate, and mixtures thereof. 3. The polymerizable composition of claim 1 , wherein the at least one polyol comprises two to six hydroxyl groups. 4. The polymerizable composition of claim 1 , wherein the at least one polyol comprises a C 2 -C 12 diol. 5. The polymerizable composition of claim 1 , wherein the at least one polyol is selected from the group consisting of ethylene glycol, diethylene glycol, propylene glycol, 1,3-propanediol, 1,2-butanediol, 1,4-butanediol, neopentyl glycol, 2-methyl-1,3-propanediol, glycerol, trimethylolpropane, ditrimethylolpropane, pentaerythritol, dipentaerythritol, erythritol, meso-erythritol, xylitol, sorbitol, ethoxylates thereof, propoxylates thereof, and mixtures thereof. 6. The polymerizable composition of claim 1 , wherein the at least one polychloroformate is present and is selected from the group consisting of ethyleneglycol bischloroformate and diethyleneglycol bischloroformate. 7. The polymerizable composition of claim 1 , wherein an equivalents ratio of total equivalents of hydroxyls to total equivalents of chloroformate is 1 to 1.5:1. 8. The polymerizable composition of claim 1 , further comprising organic peroxide. 9. The polymerizable composition of claim 8 , wherein the organic peroxide is selected from the group consisting of peroxymonocarbonate ester, peroxydicarbonate ester, diacylperoxide, and peroxyester. 10. A polymerizable composition, comprising: (a) the transesterification reaction product of an isohexide, diallyl carbonate, and at least one polyol; and (b) organic peroxide. 11. The polymerizable composition of claim 10 , wherein the organic peroxide is selected from the group consisting of peroxymonocarbonate ester, peroxydicarbonate ester, diacylperoxide, and peroxyester.
