Title:
【発明の名称】光学品質重合体の製造方法
Document Type and Number:
Japanese Patent JP2003513118
Kind Code:
A
Abstract:
A method of making improved optical quality polymers by normalizing the polymerization rates of the components of the monomer mix used is presented. The polymers produced by this process minimize the formation of separate domains and decrease the level of grit in contact lenses made from the polymers. Monomer reaction rates can be normalized by conducting the polymerization at elevated temperature.
