Abstract
A crosslinkable polymeric casting composition comprises an aromatic polyvinyl monomer such as divinyl benzene, a polythiol such as pentaerythritol tetrakis-(3-mercaptopropionate), an epoxide strain-reducing agent such as hexanediol diglycidyl ether, and, optionally, a polymerizable comonomer such as polyethylene glycol dimethacrylate.
