Aliphatic poly(propylene dicarboxylate)s: Effect of chain length on thermal properties and crystallization kinetics

Thermal decomposition of poly(propylene sebacate) and poly(propylene azelate) biodegradable polyesters: Evaluation of mechanisms using TGA, FTIR and GC/MS

“…On the contrary, the thermal degradation behavior of PLA was very complex because various reactions occurred concurrently. Thermal degradation of aliphatic polyesters based on dicarboxylic acids and diols, as well as their related nanocomposites, has also been studied [11][12][13][14][15][16][17][18][19][20][21][22].…”

Crystallization Kinetics and Melting Behaviour of the Novel Biodegradable Polyesters Poly(propylene azelate) and Poly(propylene sebacate)

“…In fact, nonisothermal crystallization of polymers is quite difficult to model, but some authors assume it can be approximated by a sequence of infinitesimally small isothermal stages, so it can be described by modifications of the Avrami equation. [16] As far as we know, apart from the work of Lotti et al, [40] where isothermal crystallization and subsequent melting of poly(propylene azelate) samples were only partially discussed, and a single work on the crystal structure of poly(propylene sebacate), [41] there is no full research dealing with solid-state and phase transformations of poly(propylene azelate) and poly(propylene sebacate). Thus, in this work, the melting behaviour of poly(propylene azelate) and poly(propylene sebacate), as well as their crystallization in isothermal and nonisothermal mode, are thoroughly studied.…”

Morphology of poly(propylene azelate) gratings prepared by nanoimprint lithography as revealed by atomic force microscopy and grazing incidence X-ray scattering

“…PPAz was synthesized by using the two-stage polycondensation procedure as previously reported [16]. PPAz was obtained with a molecular weight of M n ¼ 36,000 g/mol and a polydispersity degree of 2.5.…”

“…However, studies of crystal orientation in these types of gratings are still scarce. Aliphatic polyesters based on 1,3-propanediol can be an attractive alternative to those above mentioned specially since recently they are commercially available at low cost and in high purity [16]. Previously, we have reported on the structure and morphology of spin-coated thin films of a series of linear aliphatic polyesters [eOe(CH 2 ) 3 eOeCOe(CH 2 ) Y eCOe] based on 1,3-propanediol with different length of the acid subunit (Y ¼ 2, 3, 4 and 7) [17,18].…”
