Factors influencing orientations of covalently-attached and doped aromatic groups in stretched polyethylene films

Article Abstract:

The utility of comparing orientational parameters from doped and covalently attached groups in analyzing the factors responsible for stretch-induced orientation is demonstrated with the results. There are significant differences between the orientations of doped and covalently attached groups of the same type due to the inability of the latter to translocate between site types during film stretching.
