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.

In many cases, corrosion inhibitors would break these VES gels, and this is because inhibitors usually have oil-soluble constituents (e.g., acetylenic alcohol) or contain mutual solvents (e.g., ethylene gylcol monobutyl ether) [6].
