An ultraviolet-curable polymer composition includes (A) 5 to 100 parts by mass of syndiotactic 1, 2-polybutadiene having a 1,2-vinyl bond content of 70% or more and a degree of crystallinity of 5 to 50%, (B) 0 to 95 parts by mass of a thermoplastic polymer ((A)+(B) =100 parts by mass), (C) 10 parts by mass or less of a photoinitiator based on 100 parts by mass of the syndiotactic 1,2-polybutadiene (A) and the thermoplastic polymer (B) in total, and (D) 10 parts by mass or less of a polyfunctional acrylate based on 100 parts by mass of the syndiotactic 1,2-polybutadiene (A) and the thermoplastic polymer (B) in total. |
