Method for producing a biodegradable polyester-based polymers, and biodegradable polyester-based polymer prepared in the way

摘要

polymer manufacturing method, and relates to a polymer produced in the process, the biodegradable polyester polymer, a dicarboxylic acid compound (A), the diol compound (B) and the carbodiimide compound (C) was polymerized at 160~220 , prepolymerization generating a prepolymer, and the prepolymer under 0.1~2torr vacuum at 200~250 , including the step of condensation polymerization. .BACKGROUND
