“…Multiple endotherms have been observed in literature on some samples belonging to the 2-y series; for 2-2 and 2-4 samples [27,29] the thermal behavior has been discussed in terms of melting and recrystallization processes. The same results have been obtained for 2-12 by DSC analysis [31]. Indeed, this is behavior typical of numerous other polyesters [32,33].…”

“…The 2-12 and 6-12 samples were synthesized and studied in ref. 31. The 1 H NMR spectra confirm the structures of all the samples and the average molecular weights (M w ) are high, varying in the range from 47000 to 93000 g/mol.…”

“…To simplify the interpretation of data, we have chosen to analyze only samples containing an even number of -(CH 2 )-, in order to avoid the well known odd-even effect on the thermal properties. Some results obtained in the previous work [31] are also recovered and discussed in order to better fit our experimental data and to come to more general conclusions on the thermal behavior of this interesting class of polymers. …”

“…During the cooling scan the crystallization temperature (T cc ) and the enthalpy of crystallization (ΔH cc ) were measured; during the 2 nd scan the melting temperature (T m ) and the enthalpy of fusion (ΔH m ) were determined. The calorimetric data are collected in Table 1, where also the data measured previously on a high density polyethylene sample [31] are reported in order to better discuss the trend obtained.…”

“…In the light of these observations we have continued the work described in two previous papers, devoted to the preparation and characterization of poly(alkylene dicarboxylate)s derived from 1,12-dodecanedioc acid [30,31]. Now we have prepared other poly(alkylene dicarboxylate)s and studied the relationship existing between aliphatic chain length, crystallizability, and melting behavior.…”

Some poly(alkylene dicarboxylate)s, derived from ethanediol or 1,4-butanediol and different diacids, have been synthesized and analyzed by DSC to determine the correlations existing between the thermal properties and the length of the aliphatic chain. The polymers show crystallization and melting temperatures and enthalpies which increase as the polymethylene segments lengthen, due to the formation of more stable crystals. The samples derived from ethanediol are peculiar; they show reorganization processes during the melting and the melting temperatures are notably higher with respect to those of the other polyesters. This behavior is discussed. Isothermal analysis highlights that poly(alkylene dicarboxylate)s are fast crystallizing polymers. The Avrami analysis suggests a crystallization mechanism characterized by heterogeneous nucleation and three dimensional growth; secondary crystallizations is present only in the samples characterized by short -(CH 2 )-sequences, due to the reorganization of less perfect crystalline forms. A comparative study between the crystallization rates as a function of the undercooling is reported.

A serials of fully bio-based poly(ethylene dodecanedioate-2,5-furandicarboxylate) (PEDF) were synthesized from Dodecanedioic acid (DDCA), 2,5-Furandicarboxylic acid (2,5-FDCA), and ethylene glycol through a two-step procedure consisted of transesterification and polycondensation. After their chemical structures were confirmed by Nuclear Magnetic Resonance and Fourier Transform Infrared Spectroscopy, their thermal, mechanical, and biodegradation properties were investigated in detail. Results showed that the chemical composition of PEDFs could be easily controlled by the feeding mole ratio of DDCA to FDCA and they possessed the characteristic of random copolyester with the intrinsic viscosity ranged from 0.82 to 1.2 dL/g. With the varied mole ratio of DDCA to FDCA, PEDFs could be changed from semicrystalline thermoplastic to the completely amorphous elastomer, indicated by the elongation at break ranged from 4 for poly(ethylene 2,5-furandicarboxylate) to 1500% for amorphous PEDF-40. The amorphous PEDF-30 and PEDF-40 showed satisfactory shape recovery after cyclic tensile test, which was the typical behavior for elastomer. Enzymatic degradation test indicated that all the PEDFs were biodegradable and the degradation rate was heavily affected by their chemical compositions.

Bio‐oil contains plant, animal, fish, and micro‐algae oil, and more than 200 million tons are produced annually. However, many edible and non‐edible bio‐oils are still under development, and their value and feasibility have yet to be determined. The vast majority of bio‐oils produced in the world have a very high unsaturated fatty acid content (70–98%), which could be used as a renewable, eco‐friendly alternative to petroleum. Hydrolysis (or transesterification) with ethylene metathesis technology converts unsaturated fatty acids to C4–C30 oil fragments. These oil fragments are a sustainable chemical technology used in chemical industry platform technology and carbon dioxide abatement green chemical technology, and as a petrochemical substitute. These platform chemicals also have their own market but are used as raw materials for other products (polymers, surfactants, synthetic lubricants, plasticizers, other specialty chemicals, general purpose chemicals, biofuels, etc.). The biodegradability and biocompatibility of the polymeric materials made from the oil mean that it is also possible to develop diverse functional products with high added value such as toothpaste, dandruff treatment shampoo, and melanin pigment removal cosmetics, medical and shape memory polymer materials. According to the cradle‐to‐gate analysis for environmental impact and economics, the total carbon dioxide emission reduction per ton of soybean oil was estimated to be 1.5 kg kg−1 products. Moreover, the metathesis of soybean oil ($680/ton) with additional raw materials ($237.4) will generate a value that is 7.5 times higher at $6857. Due to the biodegradability and biocompatibility of the products made from bio‐oils, it is expected that various functional products with high added value will be developed and that industrial applicability will be greatly expanded in the near future. In addition, for the development of various derivatives, fusion and cooperative research in chemical fields such as catalytic engineering, organic chemistry, polymer chemistry, maintenance chemistry, and reaction engineering are essential. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd
