摘要：
The present invention is a process for producing a polyester-polycarbonate type thermoplastic polyester elastomer in which a hard segment consisting of a polyester constructed of aromatic dicarboxylic acid, and an aliphatic or alicyclic diol, and a soft segment consisting mainly of aliphatic polycarbonate are connected, comprising at least a step of increasing the molecular weight of an aliphatic polycarbonate diol by a reaction of an aliphatic polycarbonate diol and a chain extender, and a step of reacting aliphatic polycarbonate and a polyester constructed of aromatic dicarboxylic acid and an aliphatic or alicyclic diol in the molten state.
