Claim 15:
16. The method of claim 10, wherein the polymer is a B-staged reaction product of a second curable compound comprising a core chosen from a C6 carbocyclic aromatic ring, a C2-5 heterocyclic aromatic ring, a C9-30 fused carbocyclic aromatic ring system, a C4-30 fused heterocyclic aromatic ring system, C1-20 aliphatic, and C3-20 cycloaliphatic, and two or more substituents of formula (B-1) attached to the core:, wherein in formula (B-1): Ar1 is chosen from a C6 carbocyclic aromatic ring, a C2-5 heterocyclic aromatic ring, a C9-30 fused carbocyclic aromatic ring system, and a C4-30 fused heteroocyclic aromatic ring system; Z is a substituent independently chosen from OR1, protected hydroxyl, carboxyl, protected carboxyl, SR1, protected thiol, —O—C(═O)—C1-6 alkyl, halogen, and NHR2;
wherein each R1 is independently chosen from H, C1-10 alkyl, C2-10 unsaturated hydrocarbyl, and C5-30 aryl; each R2 is independently chosen from H, C1-10 alkyl, C2-10 unsaturated hydrocarbyl, C5-30 aryl, C(═O)—R1, and S(═O)2-R1; x is an integer from 1 to the total number of available aromatic ring atoms in Ar1; and * denotes the point of attachment to the core or to a portion of the curable compound other than the core; provided that no substituents of formula (B-1) are in an ortho position to each other on the same aromatic ring of the core.
