摘要：
A liquid composition, polymerizable by means of a free-radical route to yield optical articles endowed with a high refractive index, contains an allyl-carbonate derivative definable with the general formula: (wherein R1, X1, X2, X3, X4, X5, X6, a and b are as defined in the disclosure) and a copolymerizable monomer containing at least one ethylenic unsaturation in its molecule.
