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