Liquid composition polymerizable into organic glasses of¹high refractive index
Реферат: A liquid composition stable during storage and polymerizable radically into organic glasses having a high refractive index, containing: A) from 20 to 80% wt of a mixture of monomer and oligomers of a carbonic allyl derivative representable by the formula (I): where: x = halogen (except fluorine); a and b independently assume the values 1 or 2; n assumes values from 1 to 5 on condition that at least 10% by weight of the mixture consists of carbonic allyl oligomer derivatives (n>1); and (B) from 80 to 20% by weight of a liquid monomer copolymerizable with the component (A) and chosen from diallyl isophthalate, diallyl terephthalate, triallyl cyanurate and triallil isocyanurate. e
