Acid-catalyzed positive resist compositions which are imageable with 193 nm radiation and/or possibly other radiation and are developable to form resist structures of improved development characteristics and improved etch resistance are enabled by the use of resist compositions containing imaging polymer component comprising an acid-sensitive polymer having a monomeric unit with a pendant group containing a remote acid labile moiety.

We demonstrate the conjugation of the cancer drug doxorubicin (DOX) to poly(methacryloyloxyethyl phosphorylcholine) (polyMPC), linked by hydrazone groups, using (1) a one-pot ATRP/click sequence, and (2) a post-polymerization conjugation strategy. While the one-pot method gave polyMPC-DOX conjugates in a facile single step, post-polymerization conjugation gave higher-molecular-weight polymers with very high DOX loadings. DOX release from the polyMPC backbone was pH-dependent (faster at pH 5.0 than at pH 7.4) owing to the hydrazone linkage. Half-life values of DOX release ranged from 2 to 40 h at pH 5.0. Cell culture experiments showed that highly loaded polyMPC-DOX conjugates exhibited higher intracellular drug accumulation and lower half-maximal inhibitory concentration (IC50) values, while a polymer with 30 wt % drug loading showed a maximum tolerated dose in the range of 30-50 mg/kg DOX equivalent weight in healthy mice.
