A family of poly(ester urethane)s obtained by chain extending hydroxyl-terminated polyester prepolymers has been studied. Poly(butylene cyclohexanedicarboxylate) has been coupled in different mass ratios with two poly(butylene succinate)-based random copolymers containing ether linkages. So, five high molecular weight bio-based poly(ester urethane)s have been designed. The effect of the chemical structure and of the mass ratio of the two blocks in the final polymer has been evaluated by characterizing the materials from a molecular, thermal and mechanical point of view. In addition, envisioning a food packaging application, biodegradation in compost and measurement of the gas barrier properties have been carried out and correlated to the polymer chemical structure. The activation energy of the gas permeation process has been calculated, too. The results highlight that through the adopted strategy it is possible to prepare a new class of promising materials whose properties can be easily tailored by acting on two parameters: the mass ratio between the two prepolymers in the final material and the chemical structure of each block.

“…8,9 As above mentioned, low gas permeability is highly desirable to prolong the product shelf-life. PBCE has been chosen because of its high melting point and good barrier behavior, 6,7 while ether-oxygen containing copolymers have been considered because of their improved chain exibility and higher biodegradation rate.…”

“…In recent years, the synthesis and physical properties of poly(diethylene glycol succinate) (PDEGS), poly(triethylene dodecanoate) (PTED), and poly(butylene diglycolate) (PBDG) containing ether linkages have been reported in literature . It should be emphasized that all of these polyesters are highly hydrophilic and flexible.…”

The basic thermal properties, isothermal melt crystallization kinetics, spherulitic morphology, mechanical properties, and hydrolytic degradation behavior of a novel eco‐friendly polyester poly(butylene diglycolate) (PBDG) containing ether linkages were systematically studied with several techniques in this research. PBDG is an aliphatic polyester with high thermal stability. It had a glass transition temperature (Tg) of −25.7 °C, a melting point temperature of 65.1 °C, and an equilibrium melting point of 73.2 °C. During the isothermal melt crystallization, PBDG crystallized slowly with increasing crystallization temperature, but the crystallization mechanism did not change. Negative spherulites were observed for PBDG. The mechanical properties of PBDG were investigated from the tensile testing. As a ductile polyester, PBDG possessed good mechanical properties. PBDG also showed a fast hydrolytic degradation rate. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 44186.

The poly(butylene succinate) (PBS) copolyesters modified by 2‐methyl‐1,3‐propanediol (MPO), that is poly(butylene succinate‐co‐methyl propylene succinate) (PBMS), were synthesized by direct esterification‐melt polycondensation method. 1H NMR showed the PBMS molecules contain two repeating structural units, the butylene succinate (BS) and the 2‐methyl‐1,3‐propylene succinate (MS). The crystalline properties of PBMS were characterized by DSC, POM, and XRD. The results showed the relative crystallinity of PBMS decreases from 45.12% to 38.2%, the size of spherulites also decreases, and the crystallization ability becomes weaker compared with PBS. The water contact angle test proved the surface hydrophilicity of PBMS is improved. The impact strength of PBMS increases from 3.9 to 24.6 kJ/m2, and its elongation at break increases from 10.5% to 71.2%, and the transition from brittle fracture to ductile fracture is achieved. The study of enzymatic degradation found that the enzymatic degradation rate of PBMS copolyesters increases significantly with the increase of MPO content. Within 25 days of degradation, the weight loss rate of PBS after degradation is 38.18%, while that of PBMS reaches 100%. Finally, it was also observed the enzymatic degradation of PBS and PBMS starts from the amorphous region and abides by the regular pattern from the periphery to the middle and from the surface to the interior.
