Claim:
1. A reaction product formed from a combination comprising one or more first monomers of the formula wherein Y is selected from H, C 1 -C 30 alkyl, C 2 -C 30 alkenyl, C 7 -C 30 aralkyl, C 6 -C 30 aryl, substituted C 6 -C 30 aryl, —C 1 -C 30 alkylene-OR 1 , and —C 1 -C 30 alkylidene-OR 1 ; each R is independently selected from C 1 -C 30 alkyl, C 2 -C 30 alkenyl, C 7 -C 30 aralkyl, C 6 -C 30 aryl, substituted C 6 -C 30 aryl, —OR 1 , —C 1 -C 30 alkylene-OR 1 , and —C 1 -C 30 alkylidene-OR 1 ; R 1 is selected from H, C 1 -C 30 alkyl, C 6 -C 30 aryl, substituted C 6 -C 30 aryl, and C 7 -C 30 aralkyl; and n is an integer selected from 0 to 7; and one or more second monomers of the formula Ar—CHO, where Ar is a C 10 -C 30 aromatic moiety having at least 2 fused aromatic rings, which may optionally be substituted with one or more of C 1 -C 30 alkyl, C 2 -C 30 alkenyl, C 7 -C 30 aralkyl, C 6 -C 30 aryl, substituted C 6 -C 30 aryl, —OR 3 , —C 1 -C 30 alkylene-OR 3 and —C 1 -C 30 alkylidene-OR 3 ; R 3 is selected from H, C 1 -C 30 alkyl, and C 6 -C 30 aryl.
