Abstract

ABSTRACT: Yttrium fumaropimarat (YFPA) was synthesized with fumaropimaric acid and yttrium acetate as raw materials. The structure of the product was analyzed and characterized by Fourier transform infrared spectrometer, scanning electron microscope, energy dispersive X‐ray microanalysis, and X‐ray diffraction. The results showed that the product was amorphous state, three‐dimensional reticulation compound by the ionic bond of COO − and Y 3+ . The effect of YFPA on poly(vinyl chloride) (PVC) thermal stability was researched by means of Congo red method and heat oven aging method. The experimental results showed that YFPA was a good long‐term PVC thermal stabilizer and could greatly improve PVC thermal stability and initial stage stainability mixing calcium stearate, zinc stearate, and pentaerythrite. © 2017 Wiley Periodicals, Inc.
