The combination of Fourier transform Raman spectroscopy and thermal analysis has been proved to be adequate for the study of the quantitative structural changes which take place in amorphous poly(ethy1ene terephthalate) on stretching. The two-phase conformational model previously proposed for anneal
Comparison of the Hermans orientation functions of the amorphous fraction of PET and PA6 fibers oriented by stretching to various degrees was made. The orientation functions obtained by different methods enable one to draw conclusions about the acceptability of different methods and their correlatio
The glass transition temperature of amorphous and fractionated poly(ethylene terephthalate) has been measured by differential scanning calorimetry. The application of the Fox-Flory equation for the range of molecular weights between 37100 and 4500 gives the values of Tg~ =342.4 K and Kg=51200. The l
