    Abstract: The present invention relates to two processes for providing stable liquid blends of a) pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate, b) octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate and c) tris-(2,4-di-tert-butylphenyl)phosphite. The first process comprises preparing a solid mixture comprising about 2 parts to about 3 parts by weight a), about 2 parts to about 3 parts by weight b) and about 2 parts to about 12 parts by weight c), heating the mixture to 185° C. or higher for a sufficient time to obtain a clear liquid blend of a), b) and c), cooling the liquid blend to a temperature of from 90° C. to 140° C. and maintaining the liquid blend at a temperature of from 90° C. to 140° C. The second process comprises preparing a solid mixture comprising about 2 parts to about 3 parts by weight a) and about 2 parts to about 3 parts by weight b), heating the mixture to 90° C. or higher for a sufficient time to obtain a clear liquid mixture of a) and b), adding about 2 parts to about 12 parts by weight c) thereto to obtain a clear liquid blend of a), b) and c) and maintaining the liquid blend at a temperature of from 90° C. to 140° C. The liquid blends of a), b) and c) are stable at the temperature at which they are maintained for greater than 120 hours.
