Novel cured resin, process for production thereof, and lens composed of said resin from bis(alkyleneoxyphenyl)-diacrylate, bis(alkyleneoxyphenyl)diallyl ether, bis(alkyleneoxyphenyl)diallyl carbonate monomers |
摘要 |
A cured resin consisting substantially of a first polymer unit derived from an unsaturated compound having two terminal vinyl groups consisting of bis(alkyleneoxyphenyl)-diacrylates or dimethacrylates, bis(alkyleneoxyphenyl)diallyl ethers, and bis(alkyleneoxyphenyl)diallyl carbonates, and a second polymer unit derived from another unsaturated compound radical-polymerizable with the first-mentioned unsaturated compound, said polymer units being bonded to each other at random. The aforesaid cured resin can be producted by copolymerizing an intimate mixture consisting substantially of at least one compound selected from the first-mentioned unsaturated compounds having two terminal vinyl groups and prepolymers thereof and at least one compound selected from other unsaturated compounds radical-copolymerizable with the first-mentioned unsaturated compounds and prepolymers thereof in the presence of a radical polymerization initiator. A lens composed of the aforesaid cured resin has a high refractive index, excellent transparency and excellent fire retardancy.
