Abstract
The effects of biaxial drawing conditions on the molecular orientation and other molecular structure of poly(ethylene terephthalate) (PET) were investigated by using a new FTIR ATR attachment for dichroism studies and thermal analysis. The angular profiles of IR absorbances for the transverse electric and the transverse magnetic polarization were collected at 16 different angles around a horizontal axis and used for the orientation analysis. The results show that the orientation and the structure in biaxially drawn PET is determined in a complex way by the drawing rate, drawing temperature, and draw ratio. At slower drawing rates, higher orientation is obtained at lower drawing temperature due to the slower chain relaxation
