“…The biodegradability of PBS has been demonstrated in a liquid culture (Pranamuda et al 1995;Li et al 2005), in compost Zhao et al 2005), and in soil (Bahari et al 1998;Suhartini et al 2002). Nowadays, materials such as polylactic acid, PBS, polycaprolactone, or polybutylene adipate/terephthalate (commercially supplied by BASF under the trade name Ecoflex®) are being adopted as biodegradable mulch sheets (Kyrikou and Briassoulis 2007;Shah et al 2008).…”

Crosslinking is an effective way to improve polymer properties. This paper focuses on ultraviolet‐induced crosslinking of poly(butylene succinate) (PBS) in the presence of a photoinitiator and a crosslinking agent at ambient temperature. The effects of the concentration of photoinitiator, the crosslinking agent content, and the irradiation time on the crosslink behavior were investigated. To obtain an appropriate gel fraction in different irradiation times, 3.0 wt% of photoinitiator and 10.0 wt% of crosslinking agent were proved to be the optimum choice. Furthermore, properties such as thermal properties, dynamic mechanical property, and enzymatic degradation of PBS before and after crosslinking were examined. Differential scanning calorimetry (DSC) analysis revealed that glass transition temperature (Tg) increased with increase in gel fraction, while melting temperature (Tm) and the degree of crystallinity decreased. This may be caused by the reduced molecular chain mobility and inhibited molecular motion for crystallization in crosslinked samples. The crosslinked polymer also showed improved thermal stability and dynamic mechanical property. In addition, the introduction of crosslinking retarded the enzymatic degradation rate of PBS, but it was still biodegradable. The improved properties of crosslinked PBS will extend the application of PBS. Copyright © 2009 John Wiley & Sons, Ltd.

“…However, the low melt viscosity and molecular weight of PBS usually limit its further applications due to the highly linear chain structure , especially in areas requiring sufficient melt viscosity, such as foaming and blow molding. Thus some methods have been developed to increase the melt viscosity of PBS, such as crosslinking of PBS via peroxide , water‐crosslinking , radiation by electron‐beam or ultraviolet , chain extension and branching . Furthermore, some works on PBS foams have also been reported.…”

Biodegradable poly(butylene succinate) (PBS) foams with high performance are usually difficult to be prepared because of its lower melt viscosity. Herein, high‐melt‐viscosity PBS was firstly prepared by combining the in situ reaction between carboxyl‐ended polyester (CP) and solid epoxy (SE) both as viscosifier and strengthening agent with the presence of crosslinking agent of dicumyl peroxide (DCP) and crosslinking co‐agent of trimethylolpropane trimethacrylate. Then enhanced PBS foams were successfully prepared by the traditional chemical compression‐molding method. Furthermore, the content effects of CP/SE, blowing agent azodicarbonamide, and DCP on the properties and morphologies of enhanced PBS foams were studied in details. Results revealed that the tensile strength of the as‐prepared PBS foams was as high as 32.3 MPa with the density of 0.58 g/cm3, which was higher than that of pure PBS resin (25.6 MPa). POLYM. ENG.
