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 Ar 1 or Ar 2 . The plurality of Ar components include at least one Ar 1 and at least one Ar 2 . Ar 1 is a group represented by a formula (2) below. Ar 2 is a group represented by a formula (3) below. A molar composition ratio represented by Ar 1 / (Ar 1 + Ar 2 ) ranges from 45 mol% to 99 mol%.
