Phosphite stabilizer for lubricating base stocks and thermoplastic polymers
Abstract:
A substituted phosphite suitable for lubricating base stocks and thermoplastic polymers represented by the structure: wherein R1 is selected from the group consisting of C1-C22 alkyl and C4-C22 cycloalkyl; R2 and R3 are selected to form a C5-C18 aryl; and R4 and R5 are selected from the group consisting of H, C1-C22 alkyl, C2-C22 alkenyl, C4-C22 cycloalkyl, and C5-C8 aryl. The substituted phosphite may be combined with at least one primary antioxidant as well as other additives.
