Dielectric Analysis Of Semi-Crystalline Poly(Ethylene Terephthalate)

, 1994
Dielectric properties of poly(ethylene terephthalate) (PET) were measured over a frequency range of 10 KHz to 2.45 GHz and a temperature range of 20 to 110°C. Relaxation peaks were identified at 1) fixed frequency with variable temperatures, and 2) fixed

Degradation studies of poly (ethylene terephthalate) yarns

Communications, Faculty Of Science, University of Ankara Series B Chemistry and Chemical Engineering, 1988
Poly(ethylene terephthalate) multifilament yarn, textured yarn and staple were treated with potasium hydroxide. Time, temperature and concentration of base were seleeted as va- riables. Degradation of tlıe products was investigated in terms of percentage loss in weight, vis- cosity measurements and percent elongation at break.It was observed that ...

Selective Modification of the Product Profile of Biocatalytic Hydrolyzed PET via Product‐Specific Medium Engineering

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The product profile of enzymatically hydrolyzed PET can be modified by medium engineering and thereby adapted to a desired product. TPA, MHET or BHET can be forced as the predominant product using a basic pH (blue), 25 % ethylene glycol (EG) and IsPETasewt (green) or ≥25 % EG and LCCICCG (pink), respectively.
