Thermal properties of the photoluminescent copolymers, naphthalene-2,7-diol dimethacrylate derivatives, are presented in this paper. The materials were synthesized by bulk copolymerization of 2,7-(2-hydroxy-3-methacryloyloxypropoxy)naphthalene (2,7-NAF.DM) with four popular vinyl monomers: 2-hydroxyethyl methacrylate (HEMA), butyl acrylate (BA), divinylbenzene (DVB) and styrene (ST). As an initiator, the a,a 0 -azoiso-bis-butyronitrile was used. Thermal stabilities and degradation behaviors of the obtained copolymers were studied by means of the differential scanning calorimetry and thermogravimetric (TG/DTG, in air and in helium atmosphere) analyses. Gases evolved during the thermal treatment were monitored using the TG-FTIR coupled method. The presented copolymers can have potential application as luminophores, protective coatings or fiber-optical sensors.

Abstract-The purview of paper pivoted around the pyrolysis decomposition of forest waste (pine needle litter) by thermogravimetric analysis (TGA). Experiments were carried out in the presence of Nitrogen atmosphere. The experimental data was compared with those obtained by numerical solution of distributed activation energy model (DAEM). Asymptotic expansion is adopted to evaluate the pre-exponential factor, mean activation energy and variance. The correction factor Bi has been invoked to describe accurately the differential thermogravitmeric curves of thermal decomposition of pine needles.

“…They used their method to describe the pyrolysis of several kinds of coal. In the last years, this procedure has been thoroughly employed to analyze the kinetics of pyrolysis of different samples of coal [17,18], charcoal [19], oil shale [20], polymers [21], medical waste [22], and biomass [23 26].…”

Abstract:The thermal decomposition of biomass (pine pellets) and sewage sludge was studied using thermogravi metric analysis under an inert atmosphere and the Distributed Activation Energy Model (DAEM) was employed. The activation energy and the frequency factor that characterize the kinetics were determined for both samples. A simplification of the process for prediction of devolatilization curves was proposed, evaluating its validity for both cases. The simplified method was found to combine both simplicity and low deviations with experimental data.
