Thermal degradation of EVA and EBA—A comparison. I. Volatile decomposition products

Abstract: SYNOPSISThis is the first in a series of papers in which structural changes during thermal degradation of ethylene-vinyl acetate (EVA) and ethylene-butyl acrylate (EBA) copolymers are compared. EVA, containing 11.4 mol% vinyl acetate (VA) and EBA, containing 5.4 mol% butyl acrylate (BA), were pyrolyzed at 28OoC in nitrogen for 30 min. In another series of pyrolysis, EVA containing 1.2,2.2, and 11.4 mol% VA were treated at 15O-19O0C for 3 h. The volatile decomposition products were collected in cooled traps res… Show more

“…(This temperature interval corresponds to the first minor mass loss seen in curve 3a in Figure 3.) Further, curve 3b in Figure 3 shows a minor indication of an endothermic reaction (2508C) which is directly followed by an exothermic reaction (2808C). The endothermic reaction can most likely be associated with the ester pyrolysis of EBA, which is known to start in this temperature range [7,8]. It can be noted that the exothermic peak is not seen when using N 2 atmosphere, see the light dotted line in Figure 4.…”

“…According to McGrattan [11] and Sultan and Sörvik [12][13][14], EVA copolymers undergo a two-step decomposition: an acetate pyrolysis of the copolymer leaving a polyunsaturated linear www hydrocarbon and evolving mainly acetic acid, followed by the breakdown of the hydrocarbon backbone to produce a large number of straight-chain hydrocarbon products. It is interesting to note that the above-mentioned work of McGrattan [11] was carried out using a combination of TG/ FTIR.…”

“…Ethylene-vinyl acetate (EVA) copolymers represent the largest-volume segment of the ethylene copolymer market [9], and several authors have studied the thermal cracking of EVA copolymers with different purposes [10][11][12][13][14][15][16][17][18][19].
