Effect of alkyl chain length on the polymerization thermodynamics of 2-amino-4-(N-alkylanilino)-6-isopropenyl-1,3,5-triazines by means of DSC

Structural and thermal behavior of comb‐like polymer having n‐octadecyl side chains

“…Poly( n ‐alkyl) acrylates and methacrylates crystallize in hexagonal packing (in accordance with X‐ray studies) as characterized by a single absorption band1 at 720 cm −1 . POMA used in the present system also shows a single absorption band at 722 cm −1 , indicating that the long alkyl side chains of POMA are of the hexagonal type packing 12…”

“…POMA used in the present system also shows a single absorption band at 722 cm À1 , indicating that the long alkyl side chains of POMA are of the hexagonal type packing. 12 The primary method for monitoring pyrolysis of polymers is thermogravimetric analysis (TGA). TGA is used to determine chemical structure and the pyrolytic properties of polymers by measuring the mass volatilized as a function of time.…”

“…Somehow the crystallization of long alkyl groups in side chain polymers might be seen as a crystallization of alkanes in the presence of external constrains. The crystallization behavior of long alkyl groups in side chain polymers has been studied by different techniques10–14 and it is known that the alkyl groups in the substance can crystallize at room temperature. Otherwise, the constrains by the methacrylate backbone are still remarkable so that only one‐third of the CH 2 units in the alkyl group can crystallize easily 15…”

Cocrystallization behavior of poly(n‐docosyl acrylate) with n‐docosanoic acid by X‐ray and differential scanning calorimetry studies

“…In a recent report the conformational and crystallization behavior of poly( n ‐octadecyl methacrylate) was reported by SAXS and dielectrical spectroscopy 20. Kunisada et al21 reported the dependence of thermodynamic parameters on the alkyl chain length from DSC studies.…”
