Composition of aromatic poly(allylcarbonate), styrene materials, and crosslinker containing three or more ethylenically unsaturated groups for producing polymer of high refractive index and low yellowness

摘要

Pourable, polymerizable compositions comprising aromatic-containing poly(allyl carbonate)-functional material, styrenic material, and monomer having three or more allyl, methallyl, acrylyl and/or methacrylyl groups is free radically polymerized to produce polymerizates having high refractive index, high hardness, and low yellowness. The polymerizates are especially useful in the form of ophthalmic lenses.
