More Information
Summary:The purpose of the present invention is to provide a production method for polybutylene terephthalate (PBT) having good color tones, said method using a biological resource-derived 1, 4-butanediol (BG). This production method for PBT has: a step in which a dicarboxylic acid component and a diol component including a raw material 1, 4-BG having a nitrogen atom content of 0.01-50 ppm by mass are esterized or transesterified; and a polycondensation step in which PBT is obtained from the reaction product. The gamma-butyrolactone content in the raw material 1, 4-BG is 1-100 ppm by mass.
