Pentaerythritol‐aluminum (PE‐Al) was synthesized by a solid‐phase reaction in this study. The formation and characteristics of PE‐Al were confirmed by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). SEM images showed that the shapes of PE‐Al particles were spherical and the average size was around 23 nm. The thermal properties of rigid poly(vinyl chloride) (PVC) with PE‐Al were tested by Congo red test, thermal aging test, conductivity test, thermogravimetric analysis (TGA), and UV–visible spectroscopy test. The results showed that combination of PE‐Al, in comparison with commercial thermal stabilizers, presented an obvious improvement in stabilization efficiency of PVC. Moreover, addition of PE‐Al could significantly prolong static stability time of PVC, reduce weight loss, and improve the initial color of PVC films. © 2013 Wiley Periodicals, Inc. J. Appl. Polym.
