a) bis(allylcarbonate) of monomer diethylene glycol; b) bis(allylcarbonate) of oligomer diethylene glycol; c) tris(allylcarbonate) of monomer tris(hydroxyethyl)iso cyanurate; d) a monofunctional, unsaturated vinyl or methacryl ester monomer, is polymerized inside a mould (casting process), with fast polymerization cycle, to yield optical articles.
摘要:
A hydrogel implant article of significant softness, pliability and elasticity when dry as well as when wet consists of a random cross-linked copolymer of 2-hydroxyethyl acrylate and an alkyl acrylate. The acrylate hydrogel article is useful, in one instance, as the material to produce a scleral buckle in retinal detachment surgery.
