  A process for producing a polymer, characterized by comprising the following step (A) and step (B). (A) A step in which a polymer having repeating units represented by the general formula (1): —Ar 1 — (wherein Ar 1 represents an arylene, divalent heterocyclic, or divalent aromatic amine group having at least one C—H bond on the aromatic ring) is used as a raw material and one or more of the C—H bond(s) on the aromatic ring are converted to thereby produce a polymer having repeating units which have one or more characteristic groups X and are represented by the general formula (2): (wherein X represents a characteristic group; Ar 2 represents an arylene group, heterocyclic group, or aromatic amine group which each has a valence of n+2 and in each of which n of the C—H bonds on the aromatic ring of Ar 1 have been converted into a C—X bond; and n is an integer of 1-4) (hereinafter, this polymer is referred to as polymer having the characteristic group (X)). (B) A step in which the polymer having the characteristic group (X) produced in the step (A) is reacted with a compound having a characteristic group (Y) which reacts with the characteristic group (X) to form a bond.

  Provided are an aromatic polycarbonate copolymer and a method for producing it. An aromatic dihydroxy compound, at least one member selected from the group consisting of polyorganosiloxanes and aliphatic polyalcohols, and a dicarbonate are prepolymerized under heat to give a polycarbonate prepolymer, and the prepolymer is polymerized in a solid or swollen solid phase in the presence of a quaternary phosphonium salt serving as a catalyst to give an aromatic polycarbonate copolymer. The remaining monomer content, the acetone soluble content (that is, the low-molecular-weight substance content) and the cyclic oligomer content of the copolymer are all reduced, and the terminal hydroxyl fraction thereof is also reduced.
