Abstract:
A crosslinked oxygen scavenging polymer, comprising structure I: wherein R is selected from the group consisting of â€”H and â€”CH3; R1 and R2 are each selected from â€”H, â€”CH3, or a monomeric unit of a polymer wherein the monomeric unit comprises an ethylenic backbone and a cyclic hydrocarbon pendant group, provided at least one of R1 and R2 is the monomeric unit; M is â€”(CR32)nâ€”, wherein n is an integer from 0 to 4, inclusive; X is null or a linking group; and each R3 is independently selected from â€”H or â€”CH3; and the mole fraction of crosslinked groups is less than about 10 mol %; an ethylenic backbone; and a pendant or terminal cyclic olefinic group with structure II: wherein q1, q2, q3, q4, and r are independently selected from hydrogen, methyl, or ethyl; m is â€”(CH2)nâ€”, wherein n is an integer from 0 to 4, inclusive; X is null or a linking group; and, when r is hydrogen, at least one of q1, q2, q3, and q4 is also hydrogen.
