dc.description.abstract | The monomer methacryloyloxyethyl abietate (2) was synthesized by a simple two-step reaction starting from abietic acid. The homopolymerization of 2 and its copolymerization with MMA using AIBN as an initiator provided high-molecular-weight polymers 3-6 (10 x 10(3) < M-n < 70 x 10(3)) in high yields. These polymers were well-dissolved in organic solvents. The glass-transition temperatures, T-g, of all polymers were higher than 130 degrees C, much higher than that of PMMA. No melting points, T-m, were observed. Their decomposition temperatures were very high, as T-5 wt % loss > 300 degrees C. These results indicate that these polymers are thermally stable and glassy at room temperature. The absorption bands due to the conjugated carbon-carbon double bonds within the abietate group significantly decreased with an increase in the exposure doses. Normalized absorbance as a function of UV exposure doses nonlinearly changed because of the occurrence of a certain threshold at 1.0 J/cm(2) in all polymers. Solvent extraction experiment revealed that interchain crosslinking effectively occurred even in copolymers with relatively low amounts of the abietate group. The polymer films showed a clear transparency of more than 90%. Photolithography of the polymer films provided high-resolution pattern images | - |
