Study on thermal decomposition and oxidation kinetics of cation exchange resins using non-isothermal TG analysis

Catalytic behavior of Mn during molten salt oxidation of cationic exchange resins in Li2CO3–Na2CO3–K2CO3 melt

“…According to the previous research on the decomposition process of cationic resin, these three stages can be briefly divided. 27–30 The first stage is the evaporation of equilibrium water (30–225 °C). The resins have been adequately dried before the experiment.…”

Effect of functional groups on the thermal degradation of phosphorus- and phosphorus/nitrogen-containing functional polymers

“…For the others polymers the values were moderate and similar. Totally, the values of residues were in the range of 20 and 50 % that are typical for cross-linked functional polymers [13][14][15][16][17][18][19][20][21][22].…”

“…Unequivocally, we can say that the nature of functional groups influences the abovementioned steps of heterogeneous process. In generally, thermal stability of the polymers studied here can be compared to the stability of other commercial and in laboratory-synthesized functional polymers using appropriate characteristic temperatures [13][14][15][16][17][18][19][20][21][22].…”

“…Many researchers have studied thermal stability of cross-linked FSP with different types of pendant functional groups [13][14][15][16][17][18][19][20][21][22]. The thermal behavior of a series of commercial polymers (Purolite C104, C105 and C106, Amberlite IRC 120, etc.)…”

“…These investigations show that cross-linked FSP with carboxylic groups and their various derivatives have been explored in detail elsewhere [13][14][15][16][17][18]. The inspection of appropriate works [19][20][21] point that the literature also gives enough information about thermal stability and overall kinetic parameters of degradation process for polymers with sulfo groups, but in case of polymers with phosphorus-containing groups, literature seems to offer relatively poor information [22].…”
