Abstract
A polymerizable liquid composition includes PA1 a polymerizable poly(allyl carbonate) of an aliphatic or cyclo-aliphatic polyol; PA1 an organic peroxide generator of free radicals selected from the group of perketals, and possibly PA1 an organic dye and/or an organic photochromic compound. The compositions can be transformed, by bulk polymerization, into an organic glass which is colorless, or colored or photochromic, having good optical and mechanical characteristics.
