Abstract
A monomeric mixture for a cured polymeric material used as organic glass includes an aromatic di(meth)allyl carbonate (I), an aliphatic di(meth)allyl carbonate (II) and di(meth)allyl carbonate (III) having aromatic and aliphatic moieties. The amount of the di(meth)allyl carbonate of formula (III) is 0.1 to 10 parts by weight per 10 parts by weight of the aliphatic di(meth)allyl carbonate of formula (II). The monomeric mixture retains its uniform state without phase separation during long-term storage and gives a cured polymeric material having excellent transparency.
