Abstract
A composition at least two different phosphites, one of which is derived from an alkylated cresol, wherein the composition is a liquid at ambient conditions. The other phosphites may be derived from alkylated cresol, alkylated phenol or other alkylated hydroxyaryl compounds. The cresol may be mono-alkylated or di-alkylated with a C1-C18 alkyl group.
Claims21
A composition comprising at least two different phosphites, wherein at least one of the at least two different phosphites is derived from an alkylated cresol, and wherein the composition is a liquid at ambient conditions.
A composition comprising:
- a polymer;
- and
- a secondary antioxidant composition comprising at least two different phosphites, wherein at least one of the at least two different phosphites is derived from an alkylated cresol, and wherein the secondary antioxidant composition is a liquid at ambient conditions.
A method for forming a phosphite composition comprising at least two different phosphite compounds, the process comprising the step of reacting at least one alkylated cresol with a phosphorous halide under conditions effective to form the phosphite composition, and wherein the phosphite composition is a liquid at ambient conditions.
