The present invention relates to a polyester polymer having excellent transparency, which is produced by using a furanate compound containing an ester group derived from a biomass. The polyester polymer according to one aspect of the present invention is represented by the following formula (1). [Chemical Formula 1] Wherein R is selected from the group consisting of C 1 to C 20 alkylene, C 6 to C 20 arylene, C 3 to C 20 cycloalkylene, and C 8 to C 20 arylalkylen , and n is an integer of 1 or more. According to the present invention, by using a furanate compound containing an ester group derived from a biomass, It is possible to provide a transparent polyester polymer having thermal and mechanical properties comparable to those of the conventional polyester polymer and having less discoloration to the polymer and a furanate compound containing biomass derived ester groups at the time of production, Can be reduced. |
