摘要： A liquid composition comprising:(A) a monomeric, or essentially monomeric, diallyl-carbonate of a possibly halogenated diol containing aromatic groups; or a diallyl-ester of a halogenated aromatic bicarboxy acid;(B) a reactive monomer selected from diallyl orthophthalate, diallyl isophthalate, diallyl terephthalate, triallyl cyanurate and triallyl isocyanurate;(C) an oligomeric, or essentially oligomeric, diallyl-carbonate of diethylene glycolis polymerized under the action of a free-radical initiator, in order to yield optical articles having a high refractive index, low light dispersion, and with enhanced mechanical and color characteristics.
