Claims10
An oligomer comprising as polymerized units a first monomer comprising two cyclopentadienone moieties, a second monomer having the formula (1), and a third monomer having the formula (2)
- wherein a is the number of R groups and is an integer from 0 to 4;
- b is 1 or 2;
- each R is independently chosen from C1-4 alkyl, halo C1-4 alkyl, C1-4 alkoxy, C1-4 aralkyl, and optionally substituted C6-10 aryl;
- each R1 is independently H or optionally substituted C6-10 aryl;
- R2 is H, optionally substituted C1-10 alkyl, optionally substituted C7-12 aralkyl, optionally substituted C6-10 aryl, or R3;
- and R3 is a polar moiety selected from the group consisting of carboxyl, C2-12 aliphatic carboxylate, hydroxy C1-10 alkyl, C7-20 aryl carboxylic acid, C8-20 aryl carboxylic acid anhydride, C7-20 aryl carboxylates, C7-20 aryl amide, and C8-20 aryl imide.
An oligomer comprising as polymerized units a first monomer comprising two cyclopentadienone moieties, a second monomer having the formula (1), and a third monomer having the formula (2)
- wherein a is the number of R groups and is an integer from 0 to 4;
- b is 1 or 2;
- each R is independently chosen from C1-4 alkyl, halo C1-4 alkyl, C1-4 alkoxy, C1-4 aralkyl, and optionally substituted C6-10 aryl;
- each R1 is independently H or optionally substituted C6-10 aryl;
- R2 is H, optionally substituted C1-10 alkyl, optionally substituted C7-12 aralkyl, optionally substituted C6-10 aryl, or R3;
- and R3 is a a hydrocarbyl moiety having from 1 to 20 carbon atoms and one or more functional groups chosen from —C(O)—, —NO2, and —NR9R10, where R9 and R10 are independently chosen from H, C1-10 alkyl, C7-16 aralkyl, and C6-10 aryl.
