Polymers according to the present invention preferably comprise (i) a monomer of Chemical Formula 1 above as the first comonomer, (ii) a polyalicyclic derivative having one or more acid labile protective group(s) as the second comonomer, and (iii) at least one polymerization-enhancing monomer, preferably selected from the group consisting of maleic anhydride, maleimide derivatives, and combinations thereof. In order to increase photosensitivity, it is also preferable for the photoresist copolymer to comprise (iv) a polyalicyclic derivative having one or more carboxylic acid groups, as an additional comonomer.
