The present invention relates to phenol-free phosphites and preparation thereof. The phenol-free phosphites are obtained by reacting biphenol, and phosphorous derivatives with higher aliphatic alcohol via condensation and trans-esterification. The phenol-free phosphites of the present invention can be used as a heat stabilizer for resin so as to enhance the heat resistance of the resin during processing at high temperatures.
A polymer electrolyte composition comprising a polymer electrolyte and at least one of antioxidant selected from a group which consists of a antioxidant containing tri-valent phosphorous and a sulfur-containing antioxidant is provided as a polymer electrolyte composition superior in radical resistance property.
A fuel cell containing a polymer electrolyte membrane, wherein the polymer electrolyte membrane contains a polymer electrolyte composition that contains a polymer electrolyte and at least one antioxidant selected from the group consisting of an antioxidant containing tri-valent phosphorous and an antioxidant containing sulfur.
