In this study, we developed a series of highly stable UV absorbers for polymers which require lengthy high temperature processes, such as polyimide (PI). Three types of linear dimeric hydroxyphenyl benzotriazole derivatives were synthesized by linking monomers with different linker moieties (phenyl,...
