Method for producing a plastic lens using tertiary alkyl peroxy allyl carbonate

摘要

A plastic lens which has high hardness and excellent scratch resistance and can form a transparent and uniform reflection preventing film through vacuum deposition, is produced by mixing (a) diethylene glycol bis(allyl carbonate) with (b) at least one of organic peroxides having a decomposition temperature at selected half-life value for ten hours of not higher than 80 DEG C. and (c) at least one of specifically limited peroxycarbonates having a radical copolymerizability to the diethylene glycol bis(allyl carbonate) (a), as a polymerization initiator, and polymerizing and casting the resulting mixture in a desired lens-forming mold.
