Abstract

Disclosed are liquid stabilizer compositions useful in polyvinyl chloride formulations and which exhibit a reduced tendency to form precipitates on standing, comprising one or more aromatic ether alcohols of the formula (1): Ar-O-(CH2CH(X)O)n H wherein Ar is aryl, X
is -H or -CH3, and n is 1 to 5, and one or more thioglycolates of the formula (2): (R1)a Sn(-SCH2COOR2)4-a wherein R1 is C1-4 alkyl, a is 1-2, and R2 is C7-16 alkyl.
