Statistical and alternating Copolymers were obtained through polycondensation of different dioles and carbon acid derivates. The synthesis of block copolymers have been successful with the combination of polycondensation and ring opening polymerisation. Therefore cyclic polycarbonates or e-caprolactons were polymerised to build one block.
