## Abstract Low molecular weight 2,2‐bis(4‐hydroxyphenyl)propane polycarbonate was block‐copolymerized with the bischloroformate of polymeric glycols of a variety of structural types. Poly(ethylene oxide), polytetrahydrofuran, and hydroxy‐terminated polystyrene gave the highest molecular weight cop
