Abstract (en)
[origin: WO0109206A1] The invention is a composition comprising: 40 to 95 parts by weight of one or several monomers (I) of formula (a) wherein: R1 and R2 represent H or CH3; A represents a divalent radical of formula (b) or (c) wherein m1 and m2 represent each an integer ranging between 2 and 6; and 5 to 50 parts by weight of a monomer (II) comprising at least a urethane unit and at least two (meth)acrylate functions. The invention is useful for making optical and ophthalmic articles.
