Abstract
Certain cyclopentadienone monomers having polar moieties are useful in forming polyarylene resins having improved solubility in certain organic solvents and are useful in forming polyarylene resin layers in electronics applications.

A cyclopentadienone compound of formula (1)
- wherein each R1 is independently chosen from H, C1-20-alkyl, optionally substituted C5-30-aryl;
- each R2 is independently chosen from H, C1-20-alkyl, optionally substituted C5-30-aryl, and (PG-L)t-Ar1—;
- each PG is —C(═O)OR5;
- R5 is H;
- each Ar1 is independently optionally substituted C5-30-aryl;
- L is a single chemical bond;
- and L1 is chosen from —O—, —C1-30-ketoalkyl-, —C1-30-ketoalkyl-C6-30-aryl, —C6H4—, —C10H6—, —C6H4—C6H4—, —C6H4—O—C6H4—, —C6H4—O—C6H4—O—C6H4—, and groups of formula (1a);
- a is an integer from 0 to 3;
