“…The first with a maximum at 378°C, preceded by a shoulder at about 300°C, the second with a maximum at 445°C, and the third at 566°C. According to the literature [16,17], the poly(4VP) homopolymer exhibits one sharp degradation step, starting at *320°C, with a mass loss of 98 % at 600°C. The DTG curves for copolymers 4VP-TRIM reveal a complex degradation process, and the shapes of the curves are changing with the copolymers composition.…”

The study describes the thermal properties of porous microspheres synthesized with functional monomer 4-vinylpyridine (4VP) and crosslinking agent trimethylolpropane trimethacrylate (TRIM). Polymeric 4VP-TRIM microspheres were prepared via seed polymerization, using polystyrene microbeads as a shape template. The resulting 4VP-TRIM microspheres were in the range of 9-12 lm, with specific surface area of about 200 m 2 g -1 . The thermal properties of 4VP-TRIM materials were evaluated by thermogravimetry and differential scanning calorimetry. By TG/FTIR/MS, it was observed that new porous materials exhibited multi-staged decomposition patterns, different from poly(TRIM) microspheres. DSC and TG experiments showed that water molecules were absorbed on the materials' surface. The synthesized 4VP-TRIM microspheres exhibited rather high thermal stability. Their initial decomposition temperature was about 300°C. During the microspheres' decomposition, an evolution of carbon dioxide, water, and carbon monoxide as main gases, as well as of pyridine and aliphatic compounds, was observed. It was confirmed that the evolved pyridine accelerated the degradation of copolymeric network.

“…The two exothermic peaks at about 300°C and 375°C in the DTA curve correspond to the decomposition of lanthanum nitrate and cerium nitrate along with the degradation of PVP, which has two mechanisms of degradation involves both intra-and intermolecular transfer reactions. [8] Up to a temperature of 600°C, there was no change in weight loss, indicating the formation of pure inorganic oxide.…”

“…The degradation is assigned to the degradation of PVP. 12 Because over 390°C the PVP has degraded almost completely, the residue was thought to be almost entirely lignin. The thermal degradation temperature of blend films clearly decreases, indicating that lignin had a destabilizing effect on PVP.…”

A series of blend films with different ratio of poly(4-vinylpyridine) (PVP) to lignin were subjected to dynamic DSC and TGA measurement under nitrogen atmosphere at various heating rates. DSC curves showed that the glass transition temperatures of these blends decreased with the increase of lignin content. TGA studies indicated that the lignin content produced obvious effect on the thermal stability of these blends. The kinetic model function of the thermal decomposition of these blends obeyed the Avrami-. The degradation kinetic parameters were also obtained.
