摘要

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)
