    摘要: An ocular-lens material which comprises a copolymer obtained by polymerizing polymerizable ingredients consisting mainly of a polysiloxane macromonomer (A), a silicon-containing alkyl methacrylate (B), hydrophilic monomers (C) consisting of NVP (C-1) and other hydrophilic monomer (C-2), other monomer(s) (D), and low-molecular crosslinking monomers (E) consisting of a crosslinking monomer (E-1) having an acryloyl, vinyl, or allyl group and a methacryloyl group and a crosslinking monomer (E-2) having two or more methacryloyl groups by the casting method with heating and ultraviolet irradiation, wherein [(A)+(B)]/(C) (by weight) is 30/70 to 70/30, (A)/(B) is 25/75 to 75/25, (C-1)/(C-2) is 50/50 to 100/0, and (D) accounts for 0 to 20 wt.% of the polymerizable ingredients. The ocular-lens material has high permeability to oxygen and high mechanical strength. The surface of the material has excellent wettability by water and low-friction properties.
