Among them, physically cross-linked photodeformable main-chain azo polymers have drawn rapidly increasing interest because of their apparent advantages over the chemically cross-linked ones, including not requiring complex chemical cross-linking procedures and high recyclability/reprocessability [11,16,17,...
In this respect, itaconic acid (IA) has drawn considerable attention over recent years. This α,β-unsaturated dicarboxylic acid has found applications as an alternative monomer for polyacrylates [4,10–16]. Recently, IA has also been extensively studied in the field of unsaturated polyesters [...
