摘要： Described herein is a cast-molding process for producing contact lenses in a relatively-short curing time from a lens-forming composition, which comprises (a) at least one thiol-containing compound or component, (b) at least one metal scavenger, and (c) at least one free radical scavenger and which has a pH of from about 2.5 to about 5. The addition of a chain-transfer agent into a lens-forming composition can reduce not only the curing time of the lens-forming composition but also reduce the elastic modulus of resultant crosslinked materials (e.g., contact lenses) from the lens-forming composition. The lower pH and the addition of metal scavenger and the free radical scavenger into the lens-forming composition can ensure that the lens-forming composition to have a shelf life of at least three days.

摘要： Described are compositions and methods for inhibiting polymerization of a monomer (e.g., styrene) composition a quinone methide polymerization retarder and an oxygen-containing amine compound that is a tertiary amine or hydroxylamine. In a mixture, the oxygen-containing amine compound improves the efficacy of the quinone methide polymerization retarder and provides greater antipolymerant activity. In turn, the mixture reduces or prevents apparatus fouling and improves the purity of monomer streams.
