| titleOfInvention | Optical resin with excellent impact resistance |
| abstract | (57) [Abstract] [Purpose] An optical resin that has excellent impact resistance while maintaining physical properties such as colorless transparency, refractive index, heat resistance, light weight, solvent resistance, and light resistance, and has no sulfur odor. I will provide a. [Structure] The optical resin is composed of a polymer containing a polymer unit represented by the following general formula (1). Further, it may contain a polymer unit formed of a vinyl monomer such as (meth) acrylic acid ester. The polymer unit formed from this vinyl monomer is a polymer unit derived from a vinyl aromatic monomer such as styrene. By molding this resin by a heat curing method or an active energy ray curing method, an optical resin molded product such as a plastic lens for spectacles can be obtained. Embedded image In the formula, R 1 and R 2 are hydrogen atoms or methyl groups, n is an integer of 0 or more and 5 or less, X 1 and X 2 are oxygen atoms or sulfur atoms, A represents a group selected from an alkylene group having 1 to 8 carbon atoms, an arylene group having 6 to 12 carbon atoms, and an aralkylene group, and n = In the case expression 0 -X 1 AX 2 - in at least one sulfur atom. |
