ABSTRACT:
Compositions of bis (allyl carbonate) of linear or branched alkylene glycols, unsaturated polyester resin, and unsaturated monomer, e.g., unsaturated esters and styrene, and polymerizates produced from such compositions are described. A particular embodiment described is the composition comprising 40 weight percent diethylene glycol bis (allyl carbonate), 50 weight percent poly(ethylene maleate adipate) and 10 weight percent of dimethyl maleate, and polymerizates prepared from such composition. Such polymerizates have good optical properties and are useful as lenses, e.g., ophthalmic lenses.
