Structural, thermal and photo-physical data of azo-aromatic TEMPO derivatives before and after their grafting to polyolefins.


ABSTRACT: The data reported in this paper are complementary to the characterization of 4-(phenylazo)-benzoyl-2,2,6,6-tetramethylpiperidine-1-oxyl radical (AzO-TEMPO) and of the 4-(2-thienylazo)-benzoyl-2,2,6,6-tetramethylpiperidine-1-oxyl radical (ThiO-TEMPO) before and after their grafting to two polyethylene matrices (a copolymer ethylene/?-olefin (co-EO) and a high density polyethylene (HDPE)). Particularly the data reported in this paper confirm the structure (FT-IR analysis), the thermal (TGA and EPR) and the photo-physical (UV-vis) properties of the RO-TEMPO derivatives before and after their grafting. Herein, the FT-IR spectrum and TGA thermogram of ThiO-TEMPO were compared with those of AzO-TEMPO. Moreover, the superimposition of UV-vis spectra collected during the irradiation under 366 or 254 nm emitting lamp of AzO-TEMPO and ThiO-TEMPO in acetonitrile solution are reported. Finally, a complete DSC characterization of the functionalized POs is shown. DOI of original article: ?http://dx.doi.org/10.1016/j.polymer.2015.11.018? [1].
