STABILIZER COMPOSITION, RESIN COMPOSITION, AND MOLDED PRODUCT USING SAME

摘要

The present invention provides a stabilizer composition comprising a monoester and diester of alkylmercapto carboxylic acid of bisphenol sulfide, which is capable of maintaining good ease of handling without causing precipitation of solids even in low temperature environments. The stabilizer composition according to the present invention comprises: a diester represented by the following Formula (1):
(wherein, R 1 , R 2 and R 3 each independently represent a hydrogen atom or the like; and R 4 and R 5 each independently represent a linear or branched alkyl group having 3 to 30 carbon atoms which is optionally substituted); and a monoester represented by the following Formula (2):
(wherein, R 1 , R 2 and R 3 each independently represent a hydrogen atom or the like; and R 6 represents a linear or branched alkyl group having 3 to 30 carbon atoms which is optionally substituted)
wherein the content of the diester represented by the Formula (1) is more than 65 parts by mass and less than 80 parts by mass in a total of 100 parts by mass of the diester represented by the Formula (1) and the monoester represented by the Formula (2).
