According to our approach the synthesis of click polymers is based on the use of diyne monomers obtained by interaction of acetylenic nucleophiles (both regular, such as propargyl alcohol, 3-butyl-1-ol, and propargylamines, and strained, such as hydroxy-dibenzocyclooctyne, dibenzocyclooctyne-amines, and related compounds) with activated bis-electrophiles such as diacid chlorides, bis-chloroformates, or diisocyanates.

(2002) investigated the effect of propargyl alcohol as corrosion inhibitor copper-nickel alloy, nickel and copper in 0.5 M sulphuric acid solution [11].
Propargyl alcohol is usually taken as a standard CI for acidization and sometimes it has a significant synergistic effect with other compounds [8].
