Linear polymers were formed from yne-diyne monomers via catalytic alkyne cycloaddition in a chain-growth manner. Two monomers with significantly different reactivity produced a block copolymer by one-shot polymerization.


Electron-deficient additives such as DMAD or triyne A were employed to activate the catalysis rapidly.
