Whatever he wanted to say he would say in the trans phase only," the source said.
In the core, the decreasing content of the gauche amorphous phase leads to an increase of the total trans phase. This different conformational distribution due to the manufacturing process, is similar to the structural reorganization process that usually takes place in PET during with thermal treatment [16-18, 21, 22].
