Beschreibung
Zusammenfassung:	A photoacid generating polymer (PAG polymer) comprises i) a first repeat unit of capable of reacting with a photogenerated acid to form a carboxylic acid containing repeat unit, ii) a second repeat unit of capable of forming the photogenerated acid, and iii) a third repeat unit comprising a norbornyl ester, wherein a norbornyl ring of the norbornyl ester comprises a monovalent substituent having the formula *-L′-C(CF3)2(OH). L′ is a divalent linking group comprising at least one carbon and the starred bond of L′ is linked to the norbornyl ring. The first repeat unit, second repeat unit, and the third repeat unit are covalently bound repeat units of the PAG polymer.
