Abstract: A resin includes a repeating unit of a structure represented by a formula (FR1) below. In the formula (FR1), R are each independently an aliphatic hydrocarbon group having 1 to 6 carbon atoms, an aromatic hydrocarbon group having 6 to 12 ring carbon atoms, an alkoxy group having 1 to 10 carbon atoms, or a halogen atom; a plurality of R are optionally linked together to form a cyclic structure (including an aromatic ring and a heterocycle); and n represents an integer in a range from 0 to 3.

Abstract: A resin composition includes: a polycarbonate copolymer resin represented by a formula (1); and a polycarbonate resin having a repeating unit represented by a formula (2). Provided that a total of the polycarbonate copolymer resin represented by the formula (1) and the polycarbonate resin having the repeating unit represented by the formula (2) is defined as 100 parts by mass, a content of the polycarbonate copolymer resin represented by the formula (1) is in a range from 50 parts by mass to 95 parts by mass,

Abstract: A bischloroformate composition is represented by a formula (1) below, contains a plurality of Ar components, and has an average number of monomer units (m1), which is calculated by an expression (Numerical Expression 1) below, ranging from 1.0 to 1.99. The plurality of Ar components are each independently Ar1 or Ar2. The plurality of Ar components include at least one Ar1 and at least one Ar2. Ar1 is a group represented by a formula (2) below. Ar2 is a group represented by a formula (3) below. A molar composition ratio represented by Ar1/(Ar1+Ar2) ranges from 45 mol % to 99 mol %. average number of monomer units (m1)=1+(Mav−M1)/M2 (Numerical Expression 1)
