•Four polymers were derived from crude glycerol for the oil-sands tailing pond remediation.•Syntheses of derived polymers were carried out using microwave-assisted reaction.•Thermal degradation and reaction mechanisms were analyzed by evaluating kinetic parameters.•PDAP was the most thermally stable polymer compared to PAA121, PAA126, and PAF.•Multidimensional-diffusion describes the best rate mechanism of polymers’ degradation.
Allyl alcohol was polymerized into poly (diallyl phthalate), poly (allyl formate), and poly (allyl alcohol) using a microwave-assisted reaction. Thermal analysis identified poly (diallyl phthalate) as the most thermally stable polymer. Different reaction mechanisms were discussed in kinetics, with the three-dimensional Jander mechanism identified as the rate-determining step. Furthermore, thermodynamic parameters indicated the endothermicity and spontaneity of the degradation processes.
