환상 올레핀 모노머 및 α-올레핀 모노머로부터 얻어지는 공중합체로 이루어지는, 투명성이 우수한 필름, 시트, 판 등의 성형체를 제공한다. 본 발명은, 노보넨에서 유도되는 환상 올레핀 모노머(A)의 구조단위와, C4~C12의 α-올레핀의 적어도 하나에서 유도되는 모노머(B)의 구조단위, 를 포함하는 공중합체로서, Tg가 170℃ 이상이고, 또한 Al함량이 50ppm 이하인 공중합체로 이루어지는 성형체를 제공한다. Provided is a film, sheet, plate, or other such formed article having excellent transparency made of a copolymer obtained from a cyclic olefin monomer and an ±-olefin monomer. The present invention provides a formed article made from a copolymer having Tg of 170 °C or higher and an Al content of 50 ppm or less that is a copolymer including a structural unit of a cyclic olefin monomer (A) derived from norbornene and a structural unit of a monomer (B) derived from at least one C4-C12 ±-olefin.
