ABSTRACT:
Describes polymerizable organic compositions of from about 30 to 95 weight percent of a first monomer component which is a polyol[(meth)acryloyl terminated carbonate], e.g., diethylene glycol bis[(methacryloyloxy)ethylene carbonate)]; and from about 5 to 70 weight percent of at least one monomer component selected from: (i) an alkoxylated diol, e.g., alkoxylated bisphenol, having acrylate or methacrylate groups, e.g., dimethacrylate of bisphenol A having 25 to 35 ethoxy units, (ii) a bis[(meth)acryloyl-terminated]polyethylene glycol, and (iii) a monomer having at least three ethylenically-unsaturated terminal groups. Substantially completely cured polymerizates prepared from such compositions may be used to prepare photochromic articles, e.g., lenses, by incorporating a photochromic substance, e.g., by thermal transfer, into the polymerizate.
