| Abstract: | We report the recent progress in the preparation of functional poly(disubstituted acetylene)s (PDSAs) through post‐polymerization modification routes. The metathesis polymerization of disubstituted acetylene monomers activated by Mo/W–Sn complex catalysts, which do not tolerate highly polar functionalities, was assumed to be a key step in the polymer synthetic procedures. We and other groups have explored several approaches to prepare PDSAs with latent reactive functionalities, which are inactive to Mo/W–Sn complex catalysts but can be used as highly reactive sites for post‐polymerization modification. Click chemistry, Michael‐type addition reactions, the use of activated esters and other strategies are demonstrated by recently published examples. These works indicate that post‐polymerization modification is an efficient route to the synthesis of various functional PDSAs. |
