Jan 03, 2022· Antioxidant D37 is a high-efficiency and long-lasting new type of anti-ozone and anti-aging agent, which has excellent protection against static and dynamic ozone aging, The molecular formula of antioxidant D37 is shown in Fig. 2. This work uses this kind of antioxidant to study the ozone aging protection effect of SIBR.
A multifunctional additive (1-allyl-3-(4-(phenylamino)phenyl)thiourea, APPT) with amine, thiourea and allyl groups was synthesized by reacting N-phenyl-p-phenylenediamine (PPD) with allyl isothiocyanate (AITC).The chemical structure of APPT was confirmed by FTIR, UV–Vis, 1 H NMR, 13 C NMR and elemental analysis. When employed in styrene-butadiene
