Jiang, Siyuan; Liu, Yufei; Zou, Xiaoyu; He, Min; Zhang, Kai; Xu, Guomin; Qin, Shuhao published the artcile< Synthesis and application of new macromolecular hindered phenol antioxidants of polyamide 6>, Product Details of C4H8O, the main research area is nylon 6 antioxidant hydroxyphenyl propionate phenylmaleimide alternting copolymer preparation.
The two macromol. antioxidants, P(3,5-di-tert-butyl-4-hydroxy cinnamic acid-N-phenylmaleimide) (PCN) and P(3-butene-1-yl-3,5-di-tert-Bu -4-hydroxyphenyl propionate-N-phenylmaleimide) (PPN) were designed and synthesized via free radical copolymerization The structures of the resulting PCN and PPN antioxidants were characterized by Fourier transform IR spectroscopy, NMR spectroscopy (1H NMR), and gel permeation chromatog. In addition, the effect of the two macromol. antioxidants on the thermal oxidation aging resistance of polyamide 6 (PA6) was studied. According to the anal. of differential scanning calorimetry, thermogravimetric anal., dynamic mech. anal., dynamic viscosity, and the mech. property of PA6 and its blends, these two types of macromol. antioxidants protected the mol. chain of PA6 from breaking, protected the crystallization of PA6 and maintained the stability of PA6 crystal form, improved the activation energy of thermal degradation and thermal stability of PA6, enhanced the strength and elasticity of PA6 and maintained the mech. properties of PA6 during aging to a certain extent.
Journal of Applied Polymer Science published new progress about Antioxidants. 627-27-0 belongs to class alcohols-buliding-blocks, and the molecular formula is C4H8O, Product Details of C4H8O.
