Chloroform, maleic anhydride (MA) and butyl acrylate (BA) were purchased from Sigma-Aldrich and used without further purification, poly(2-ethyl-2-oxazoline) (PEtOx) was obtained from Kremer Pigmente (Munich, Germany). Dimethyl vinyl ethynyl carbinol (DVC, also known as Nazarov's carbinol), was obtained from the Nairit plant CJSC (Yerevan, Armenia), was additionally purified via vacuum distillation and subsequently stabilized by adding of 0.1 % of hydroquinone (HQ) before further use. Crude tert-butyl hydroperoxide (TBHP) with concentration of 65-70% has been synthesized in the laboratory of Organic Chemistry Chair at Lviv Polytechnic National University.
