  • ULTRAVIOLET-RAY ABSORBING POLYMER, FORMATION RESIN COMPOSITION, AND FORMED BODY
    Publication number: 20210380743
    Abstract: An ultraviolet-ray absorbing polymer containing a monomer unit represented by general formula (12) below and a monomer unit derived from a monomer represented by general formula (1) below. In general formula (12), R6 represents any one selected from a group consisting of a hydrogen atom and a methyl group, U represents a hydrocarbon group, and the hydrocarbon group includes a skeleton absorbing ultraviolet rays and optionally contains a heteroatom. In general formula (1), R16 represents any one selected from a group consisting of a hydrogen atom and a methyl group, and Z represents any one selected from a group consisting of a chain hydrocarbon group having 10 or more carbon atoms and a polycyclic hydrocarbon group having 10 or more carbon atoms.
