Claim Text:
1. A polymer comprising, based on 100 mole percent of total repeat units, 60 to 100 mole percent of photoacid-generating repeat units, wherein each of the photoacid-generating repeat units comprises (a) photoacid-generating functionality and (b) base-solubility-enhancing functionality selected from the group consisting of tertiary carboxylic acid esters, secondary carboxylic acid esters wherein the secondary carbon is substituted with at least one unsubstituted or substituted C 6-40 aryl, acetals, ketals, lactones, sultones, alpha-fluorinated esters, beta-fluorinated esters, alpha,beta-fluorinated esters, polyalkyleneglycols, alpha-fluorinated alcohols, and combinations thereof: wherein the photoacid-generating repeat units have the structure wherein R L m is independently in each of the repeat units 0 or 1; L Z Q wherein at least one of L
