Polybutylene succinate (PBS) ..

J.; Zhu, B.; Dong, T.; Inoue, Y.* Temperature-Dependent Polymorphic Crystalline Structure and Melting Behavior of Poly(butylene adipate) Investigated by Time-Resolved FTIR Spectroscopy.

The comprehensive properties of poly (butylene succinate) (PBS) are comparable to the conventional polypropylene and polyethylene, and it is considered to be a promising bio-based polymers [, ]. However, its melt strength/viscosity and crystallization rate are low, which lead to a poor blow-molding processability. A cross-linking of PBS should be an effective way to address those issues [-]. The traditional cross-linking modification is achieved by post-processing. Not only extra equipment is needed, but also some gels are formed during modification, which will influence the reprocessability and biodegradability of PBS. If we make PBS slightly cross-linking at the polycondensation stage instead of post-processing, the crosslinking degree is so low as not to affect PBS further thermal processing.

Nanocomposites: synthesis, structure, properties and …

Diacetylene group is prone to cross-linking reaction under UVirradiation or at high temperature [-]. In this study, a functional monomer containing a diacetylene group, dimethyl 4, 40- (buta-1, 3- diyne-1, 4-diyl) dibenzoate (DA), was designed and synthesized. It was found that DA can partly cross-linked at the melt polymerization temperature ( in Supporting information), and therefore a small amount of DA is copolymerized with 1, 4-butanediol, and dimethyl succinate to prepare PBS copolyesters. It is expected that the slightly-cross-linking reaction caused by DA will increase the melt strength/viscosity and the crystallization rate of PBS.

1, 4-Butanediol (BDO, AR grade), and zinc acetate (Zn (OAc)2, AR grade) were purchased from Kelong Chemical Corporation (Chengdu, China). Dimethyl succinate (DSA, AR grade) was purchased from Alfa Aesar Chemical Corporation (Tianjin, China). Tetrabutyl titanate (TBT), used as a catalyst, was also provided by Kelong Chemical Corporation, and dissolved in anhydrous toluene to prepare 0.2 g/mL solution. Methyl 4-iodobenzoate (AR grade), ethynyltrimethylsilane (AR grade), copper (I) iodide (CuI, AR grade) and bis (triphenylphosphine) palladium (II) chloride (Pd (PPh3)2Cl2, AR grade) were purchased from Yinuokai Chemical Corporation (Beijing, China). Copper (I) chloride (CuCl, AR grade), dimethyl sulfoxide (DMSO, AR grade), potassium carbonate (K2CO3, AR grade), triethylamine (Et3N), tetrahydrofuran (THF), hydrochloric acid (HCl), methanol and ethanol were purchased from Kelong Chemical Corporation. DA monomer (described in Supporting information) is synthesized according to the following synthetic procedures ().
