摘要: When molding shaped articles such as contact lenses from monomeric mixtures containing silicone monomers and hydrophilic monomers, the wettability of the resulting article is improved by using a mold material produced from a resin comprising a copolymer of an alpha, beta, olefinically unsaturated mononitrile and at least one comonomer to enhance melt processability.
