Copolycarbonates having improved flowability

摘要

A copolycarbonate having improved flowability and processes for its preparation is disclosed. The molecular structure of the copolycarbonate includes at least one unit derived from at least one dihydroxy compound selected from the group consisting of compounds of formula (1) in which R¹ and R² each independently of the other represents hydrogen or linear or branched C₁-C₁₀-alkyl, and X represents O or S. preparation of polycarbonates.
