This pro­ duction method for PBT has: a step in which a dicarboxylic acid component and a diol com­ ponent including raw a material 1, 4-BG hav­ ing nitrogen a atom content of 0.01-50 ppm by mass are esterized or transesterified; and a polycondensation step in which PBT is ob­ tained from the reaction product. The gam- ma-butyrolactone content in the raw material 1, 4-BG 1-100 is ppm by mass. £*r*\"3PBT0>i![ii£&-efcoT\ flul olip pm-efc-5 B P TCDiiii (57)^: 1 , 4 — — ffll fl/7$l/-h (PBT 5 Olip pm©Ifi1 ;UJ ^bPBT jsasa*© (BG) ^ U T U > ) tt&o * o. o 1 ~ , 4-BG liiXr;!/ -€\"CDJ5.)S^ jy. ft X fM <t 1 ~ 1 0 WO 2013/183590 A11 lllll llllllll II llllll lllll III lllll lllll III III III lllll lllll lllll lllll llll llll lllllll llll llll MZ, NA, NG, NI, NO, NZ, OM, PA, PE, PG, PH, PL, PT, QA, RO, RS, RU, RW, SC, SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW.
