“…There is an optimal range (30-55 mol% terephthalic acid), which is related to molecular weight and especially the crystalline content of PBAT [111,112]. Biodegradability enhances as crystallinity decreases [48,113]. The addition of natural fillers can enhance the disintegration tendency of the PBAT-based composites in the soil.…”

There is growing interest in biodegradable polymers (BP), in particular poly(butylene adipate‐co‐terephthalate) (PBAT), due to environmental problems associated with the disposal of non‐biodegradable polymers into the environment. However, high production cost and low thermo‐mechanical properties restrict the use of this sustainable material, making its biodegradability advantageous only when it is decisively required. The addition of different compositions of monomers and selective addition of natural fillers have been reported as alternatives to develop more accessible PBAT‐based bioplastics with performance that could match or even exceed that of the most widely used commodity plastics. This review explores the recent progress of the applications and biodegradation of PBAT. The addition of natural fillers and its effect on the final performance of the PBAT‐based composites is also reported with respect to improving the properties of composites. The advance of polymerization reaction engineering combined with sustainable trend offers great opportunities for innovative green chemical manufacturing. POLYM. ENG.

“…Jin and coworkers reported that the biodegradability of PBS that was crosslinked with benzoyl peroxide was remarkably decreased. 16 Teramoto and coworkers found that the biodegradability of the crosslinked PBS copolymer was significantly suppressed not only by crosslinking but also by the crystallinity, even though crosslinking did not completely destroy biodegradability. 17 In this work, we prepared crosslinked poly(butylene succinate) (PBS) foams with closed-cell structures using two types of branching agents.…”

In order to obtain crosslinked poly(butylene succinate) (PBS) foams with a closed-cell structure, a commercial-grade PBS was first modified in the melt using two different branching agents to increase the melt viscosity. The rheological properties of the branched and crosslinked PBS were examined by varying the amount of the branching agents. The complex viscosity of the crosslinked PBS increased with increasing amount of the branching agent. However, it decreased with increasing frequency. When 2 phr of the branching agent was added to PBS, the storage modulus (G') was higher than the loss modulus (G") throughout the entire frequency range, showing that the addition of a branching agent increases the melt viscosity and elasticity of PBS effectively. Closed-cell PBS foams were prepared by mixing the chemical blowing agent with the crosslinked PBS. The effect of the foaming conditions such as temperature and time, and the amount of the crosssslinking agent on the structure of the expanded PBS foams were also investigated.

ABSTRACT:Ring-opening copolymerizations of succinic anhydride (SAn, 1) or maleic anhydride (MAn, 2) with propylene oxide (PO) were carried out by using magnesium diethoxide (Mg(OEt) 2 ) as a catalyst. The unsaturated polyester (P2a) was found to have only Z-configuration around a C=C double bond from its 1 H and 13 C NMR spectra. Isomerization reaction of P2a from Z-to E-configuration was performed in 1,2-dichloroethane with a catalytic amount of morpholine. Thus unsaturated polyesters, P2b-e, having the same molecular weight but the different ratio of Z-/E-configuration could be optionally prepared from one original polymer P2a by controlling isomerization reaction time. Biodegradability of these polyester samples was evaluated from their biochemical oxygen demand (BOD) values in the presence of an activated sludge. Polyester P2a was hardly degraded during measurement. However, polyesters P2b-e, partially containing E-configuration of the C=C double bond, degraded considerably faster than P2a itself. The biodegradability of saturated polyester P1 was also examined to compare with the P2-series.KEY WORDS Biodegradability / Unsaturated Polyester / Geometrical Isomer / Ring-Opening Copolymerization / Cyclic Acid Anhydride / Propylene Oxide / Synthetic polymeric materials have provided many advantages in our daily life for the last century, and become one of the most important materials. When once almost all of synthetic polymers are disposed after use, however, those cause serious environmental problems. Thus, biodegradable polymers have received much attention in recent years as one of the answer to solve the problems. In fact, biodegradable polymers, especially aliphatic polyesters, have been widely investigated by many scientists in the world.In spite of a large number of studies on biodegradability of polyesters, little attention has been given to unsaturated polyesters. 1-6 Tokiwa and Suzuki reported that a few unsaturated polyesters containing 2-butenediol unit could be hydrolyzed by lipase. 1 On the other hand, slightly cross-linked unsaturated polyesters, poly(hexamethylene fumarate) and poly(cis-2-butene fumarate), were hardly hydrolyzed by lipase.A carbon-carbon double bond in unsaturated polyesters has two geometrical isomers (Z-and Econfiguration), and such difference should affect their biodegradability. In controlling the biodegradation rate of polyester, it is very helpful to make geometrical effects clear. In our previous paper, 6 it was shown that in comparison with saturated polyesters, the ef- † To whom correspondence should be addressed. ficient degradation was prevented by introducing Zconfiguration of C=C double bond in the unsaturated polyesters but introducing E-configuration did not affect so remarkably. However, the variety of samples was limited because of the difficulty in preparation of samples having the same molecular weight and the different Z/E ratio. Although polycondensation method of unsaturated acid anhydrides with diol in the presence of acid as a catalyst was employed in prev...
