Poly(Butylene Terephthalate) (1) (Eluent: HFIP) (HFIP-805 + HFIP-803)

Print Friendly, PDF & Email

 

Poly(butylene terephthalate) was analyzed using GPC HFIP-805 + HFIP-803 (columns for GPC separation). PBT is a polyester resin used in a wide variety of fields. This chromatogram shows that small amounts of oligomers may affect the characteristics of PBT resin.
