Patent ID: 8053515

Claim:
A polymer comprising a first type and a second type of repeat unit represented by Formula I: where X is selected from —CH 2 —, —CH 2 —CH 2 —, or —O—; m is an integer from 0 to 5; and where for the first type of repeat unit one of R 1 , R 2 , R 3 , and R 4 is a maleimide containing group represented by Formula II: where A is a linking group selected from methylene, a linear or branched C 2 to C 6 hydrocarbyl, halohydrocarbyl or perhalocarbyl, or a substituted or unsubstituted C 5 to C 12 cyclic or polycyclic hydrocarbyl, halohydrocarbyl or perhalocarbyl, and R 5 and R 6 are each independently selected from H, methyl, ethyl, or n-propyl, and where the others of R 1 , R 2 , R 3 , and R 4 are selected from H, a linear or branched C 1 to C 25 hydrocarbyl, halohydrocarbyl or perhalocarbyl; and where for the second type of repeat unit one of R 1 , R 2 , R 3 , and R 4 is a hindered aromatic group represented by Formula (D) where A 2 is a linking group selected from methylene, a linear or branched C 2 to C 6 hydrocarbyl, halohydrocarbyl or perhalocarbyl, or a substituted or unsubstituted C 5 to C 12 cyclic or polycyclic hydrocarbyl, halohydrocarbyl or perhalocarbyl, C 2 to C 12 ester, C 1 to C 12 amide, C 1 to C 12 sulfide, or a combination thereof; each Y is independently a functional group such as OH and SH; y is an integer from 1 to about 3; each R 20 is independently a C 1 to C 12 alkyl (straight or branched) or cycloalkyl group (substituted or unsubstituted); and x is an integer from 1 to about 4; a C 8 or greater alkyl group; a C 4 or greater halohydrocarbyl or perhalocarbyl group; a C 7 or greater aralkyl group; or a heteroatom hydrocarbyl or halohydrocarbyl group, with the proviso that the heteroatom hydrocarbyl or halohydrocarbyl group does not comprise an epoxy group.
