Document Type and Number:
Japanese Patent JPH01500413
Kind Code:
A
Abstract:
An improved mold apparatus and spin casting method adapted for use in the molding of precisely configured articles, e.g., a contact lens, from a liquid polymerizable reaction mixture containing at least one volatile component is disclosed. Loss of this volatile component from the reaction mixture is prevented by providing a separate reservoir filled with a liquid volatile substance which volatilizes and fills the space above the liquid polymerization mixture.
