Patent ID: 11674041

Abstract:
A composition having a polymer having a polymer matrix, a first stabilizer molecule within the polymer matrix, and a second stabilizer molecule within the polymer matrix, the first stabilizer molecule having the structure: wherein each R1-R4 is independently selected from the group consisting of C1-22 alkyl, C6-40 cycloalkyl, C2-20 alkyl glycol ether, and Y—OH; each Y is independently selected from the group consisting of C2-40 alkylene, C2-40 alkylene lactone, and C6-40 cycloalkylene; m is an integer ranging from 1 to 100; and x is an integer ranging from 1 to 1,000; the second stabilizer molecule is a monophosphite having an aryl moiety; wherein the claimed composition does not include a hindered phenolic antioxidant, lactone stabilizer, or hydroxylamine stabilizer.
