APPENDIX
1. A liquid composition which is polymerizable, by means of
radical polymerization with low shrinkage, into organic glasses,
comprising the product obtained fro the transesterification of a
diallylcarbonate (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, wherein the molar ratio
(A)(B+C) ranges from 2.5/1 to 4/1 and the quantity of (C) in the
mixture (B+C) ranges from 5% by weight to 20% by weight with
respect to the total weight of said mixture (B+C).
