Process for casting polymer rods |
| abstract |
Polymeric rods suitable for manufacturing contact lenses may be improved by casting the rod in Teflon or in a Teflon-coated tube. Contact lens materials containing NVP as a monomer are preferably cast in tubes made of Teflon or having Teflon coating on the interior surface. The rods thus cast are substantially free of strain, have a uniform diameter, a smooth, continous exterior surface and an absence of voids therein. When initial polymerization is conducted at a moderate temperature in a water bath, the mixture is polymerized homogeneously to provide superior uniformity. |
