Oprea, Stefan published the artcileThe effects of the inclusion of 1,2,4-triazole derivatives into the main chains of the polyurethane urea exposed to UV radiation, HPLC of Formula: 1455-77-2, the main research area is polyurethane urea triazole UV irradiation mech property surface morphol.
Linear polyurethane urea containing 1,2,4-triazole segments was obtained by polyaddition of the 3,5-diamino-1,2,4-triazole (DATA) to urethane prepolymer. Also, three crosslinked polymers with different crosslinkers (2,4,6-triaminopyrimidine (TAP), glycerin (Gly), castor oil (CO)) were synthesized. Thermogravimetric anal., of the obtained polymers, indicated good thermal stability up to 310°C. The polyurethane urea chem. structure was confirmed by FTIR anal. The glass transition temperatures (Tg) of these polymers, measured by differential scanning calorimetry (DSC), were found in the range of -52°C to -56°C. These values were not significantly influenced by the structure of the hard domain and the intermol. interactions. The tensile testing showed that the inclusion of 1,2,4-triazole in polyurethane structure substantially improves the tensile strength up to 58 MPa. The obtained polyurethane urea presents surface slight hydrophobic and low interfacial tension. The pos. effect of the 1,2,4-triazole segment from the polymer main chain in the UV aging process of these polymer materials has been studied. After exposure to UV radiation, few changes were observed in the mol. structure, in the surface morphol. and the mech. properties.
