    摘要: Stabilizer compositions for rigid polyvinyl chloride resin compositions are provided comprising an antimony mercaptocarboxylic acid or ester and a mercaptocarboxylic acid ester in amounts within the range from about 90 to about 25 parts antimony mercaptocarboxylic acid or ester and from about 10 to about 75 parts mercaptocarboxylic acid ester; the amount of mercaptocarboxylic acid ester being selected within these ranges to synergize the stabilizing effectiveness of the antimony mercaptocarboxylic acid or ester.Rigid polyvinyl chloride resin compositions also are provided having their resistance to the development of early discoloration enhanced by a stabilizing amount of the antimony mercaptocarboxylic acid or ester and mercaptocarboxylic acid ester, the synergistic effect being particularly evidenced in rigid polyvinyl chloride resin compositions containing both an ortho-dihydric phenol and an alkaline earth metal carboxylate, such as catechol and calcium stearate.
