    摘要: Liquid composition which can be polymerized into organic glasses, by means of radical polymerization with low shrinkage, comprising the product obtained from the trans-esterification of a diallycarbonate (A) with a mixture of one or more linear or branched aliphatic diols (B), containing from three to ten carbon atoms in the molecule, with a linear or branched aliphatic polyol (C), containing from four to twenty carbon atoms and from three to six hydroxyl groups in the molecule. The molar ratio A/(B+C) in the above polymerizable liquid composition ranges from 2/1 to 5/1 and the quantity of (C) in the mixture (B+C) is equal to or less than 25% by weight with respect to the total weight of this mixture.
