“…This is related to the thermal destruction of the poly(ethyl 2‐cyanoacrylate) chains. The degradation process is similar to that noted by other researchers 20,22,28 . It has been suggested that the thermal degradation of this polymer was predominantly due to an unzipping polymerization process initiated from the polymer chain terminus 22,28 …”

“…The unique degradation behavior of PECA could be used to produce a variety of carbon nanostructures for several applications, including catalysis, energy storage, superhydrophobic coatings and sensors. 22 Kinetic analysis is performed in order to enrich practical and theoretical knowledge. From a practical point of view, using such analysis, we are able to determine the speed of a process under consideration and the lifetime of the studied materials.…”

“…Vapor‐phase polymerization of ECA in a humidified area was used for the preparation of a graphene/PECA composite electrode with strong electrocatalytic activity and substantially improved signal‐to‐noise characteristics 21 . Damodar et al 22 . have recently synthesized nitrogen‐doped multi‐wall carbon nanotubes using ECA as a nitrogen‐containing carbon precursor and a catalyst‐free, direct pyrolysis of carbon precursor process due to the unique morphological changes and structural transformations of PECA in deionized water, as well as the peculiar degradation behavior of PECA during the heat treatment process.…”

A thermogravimetric study of poly(ethyl cyanoacrylate) nanofibers was carried out at five heating rates with a linear increase in the temperature in a nitrogen atmosphere. The data provided by the thermogravimetric study were used to evaluate the kinetics of the degradation process using three isoconversional methods. Considering that the kinetic parameters of the process depend on the reaction mechanism, various approaches were applied in order to determine the most probable mechanism function. In this respect, the mechanism of thermal degradation of poly(ethyl cyanoacrylate) is a phase boundary reaction with cylindrical symmetry (F 0.5 function) as demonstrated by the z(⊍) master plots method, iso-temperature method and isoconversional method. On their basis, the values of the kinetic triplet (E a , A and the shape of the most appropriate f(⊍) function) of the process were obtained, and subsequently the thermodynamic functions of the activated complex formation were calculated. The thermal stability of the polymer was predicted according to the integral procedure decomposition temperature.
