摘要：

Poly[4-((tert-butoxycarbonyl)oxy)styrene-sulfone] (TBSS) was synthesized by a thermally induced radical copolymerization of 4-((tert-butoxycarbonyl)oxy)styrene and sulfur dioxide using AIBN as the initiator. The effect of polymerization conditions such as temperature, monomer feed ratio, and monomer concentration on the copolymer molecular weight and composition was studied. The styrene-sulfone monomer sequence distribution was determined by NMR techniques, and the materials were found to be random copolymers of 4-((tert-butoxycarbonyl)oxy)styrene and SO2. The monomer triad sequence distribution was identical for copolymers of equivalent composition prepared by different synthetic routes. The onset temperature for the thermal deprotection reaction decreases somewhat with increased incorporation of SO2 relative to the parent styrene polymer, while the T(g) increases. For imaging applications, it was determined that the extent of tert-butoxycarbonyl removal at a given dose decreased with increasing SO2 content; a phenomenon that was ascribed to differences in the catalytic chain length and diffusion distance of the photogenerated acid.
