“…The thermal resistance of adsorbents used in chromatographic methods, such as poly(styrene-divinylbenzene), polyacrylic acid, acrylicdivinylbenzene copolymers, and dendrimeric materials was reported in literature [12][13][14][15]. In our studies, we intended to obtain porous microspheres of 4-vinylpyridine crosslinked with trimethylolpropane trimethacrylate.…”

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.

“…Hence, knowledge of the thermal behavior of cation exchange resins is necessary. Abundant data exist on the thermal degradation of anion exchange resins [23][24][25] and on carboxylic cationites with low acidity [26][27]; literature seems to offer relatively poor information on polystyrene-divinylbenzene sulfonic cationites [28][29][30][31][32][33]. Therefore, in the present investigation thermal degradation of strongly acidic sulfonic cationites was performed to understand the degradation steps and to compare the relative thermal stability.…”

The thermal degradation of some sulfonic cationites namely Amberlite IR-120, Indion-223 and Indion-225 was investigated using instrumental techniques like thermal analysis (TG) and Scanning Electron Microscopy (SEM). Fourier Transform Infrared Spectroscopy (FTIR) was used to characterize the resins degradation steps. The sulfonic cationites undergo degradation through dehydration, followed by decomposition of sulfonic acid functional groups liberating SO 2 . The thermogravimetric analysis of above cationites at higher temperature up to 520˚C, show mass loss of 61.61% and 25.43% respectively for Indion-223 and Indion-225, while Amberlite IR-120 cationite get burned off completely.

In the present study the thermal behavior of phosphorus-and phosphorus/nitrogen-containing functional polymers was studied. The polymers were synthesized via oxidative chlorophosphorylation reaction of butadiene rubber and were subsequently subjected to hydrolysis, aminolysis and/or alcoholysis in order to introduce appropriate functionalities. The successful modifications of the polymer and presences of functional groups were determined using Fourier Transform Infrared Spectroscopy. It was found that the product of hydrolysis of the modified butadiene rubber contains acidic groups in its structure, the products of aminolysis and alcoholysis contain both acidic and amine and/or an alcohol derived moieties. The kinetic analyses of the thermal decomposition reaction were evaluated using thermogravimetric analysis and subsequently Friedman and Ozawa-Flynn-Wall methods. It was shown that degradation of the cross-linked polymers depends on the attached functional groups. The mass loss and the overall kinetic parameters of degradation showed complex mechanisms which characterize these thermal reactions.
