摘要

A bischloroformate composition, which is represented by the following general formula (1), contains a plurality of Ar components, and has an average number of monomers (m1) obtained by the following formula (Equation 1) of 1.0 or more and 1 99 or less, and the plurality of Ar components are each independently Ar ₁ or Ar ₂ , and the plurality of Ar components include one or more of Ar _{1 and} one or more of Ar _2. Ar ₁ is a group represented by the following general formula (2), Ar ₂ is a group represented by the following general formula (3), and is represented by Ar ₁ / (Ar ₁ + Ar ₂ ). The bischloroformate composition is characterized in that the molar composition is 45 mol% or more and 99 mol% or less. [Chemical 1] [Chemical 2] [Equation 1] Average number of masses (m1) = 1 + (Mav−M1) / M2 (Equation 1)
