Although there are a lot of papers published on tautomeric studies of different organic compounds, no much works are related with tautomerics equilibria in polymers. For example, Czech studied metal chelate zirconium acetylacetonate (ZrACA) added into acrylic polymers with self-adhesive properties [2]. These acrylic polymers, known as acrylic pressure-sensitive adhesives (PSA), were crosslinked with ZrACA to obtain acrylic self -adhesives and to study the crosslinking reaction between carboxylic groups of the polymer chain and metal chelate crosslinking agent. The tautomeric equilibrium in this reaction is very important because these reactions occur through tautomeric forms. We consider that tautomerics equilibria in polymers could be responsible for important properties and applications. That is why the aim of our work was the study of tautomerics equilibria in styrenic copolymer including a comonomer with tautomeric â-ketonitriles form.
