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, R1, R2 and R3 each independently represent a hydrogen atom or the like; and R4 and R5 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, R1, R2 and R3 each independently represent a hydrogen atom or the like; and R6 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). |

1. A stabilizer composition, comprising:
a diester represented by the following Formula (1): (wherein, R1, R2 and R3 each independently represent a hydrogen atom, an alkyl group having 1 to 18 carbon atoms, a cycloalkyl group having 3 to 18 carbon atoms, or an aryl group having 6 to 30 carbon atoms which is optionally substituted with an alkyl group, an alkoxy group, an alkenyl group, an alkenyloxy group or a hydroxyl group; and R4 and R5 each independently represent a linear or branched alkyl group having 3 to 30 carbon atoms which is optionally substituted with an alkoxy group, an alkenyl group, an alkenyloxy group, a hydroxyl group or a cyano group); and a monoester represented by the following Formula (2): (wherein, R1, R2 and R3 each independently represent a hydrogen atom, an alkyl group having 1 to 18 carbon atoms, a cycloalkyl group having 3 to 18 carbon atoms, or an aryl group having 6 to 30 carbon atoms which is optionally substituted with an alkyl group, an alkoxy group, an alkenyl group, an alkenyloxy group or a hydroxyl group; and R6 represents a linear or branched alkyl group having 3 to 30 carbon atoms which is optionally substituted with an alkoxy group, an alkenyl group, an alkenyloxy group, a hydroxyl group or a cyano group), wherein the content of said diester represented by said 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 said diester represented by said Formula (1) and said monoester represented by said Formula (2). |
