“…Additionally, we also compared the mechanical properties of PBAT/TPS (70/30) composite films prepared by other researchers with us. It can be seen that compared to the work of others, , our result has advantage in tensile strength. The composites prepared by crosslinking reaction have a suitable elongation at break due to the fact that crosslinking restricts the slip of the macromolecular chain segments.…”

Starch, as an inexpensive natural polymer, can be used as a filler to effectively reduce the cost of poly(butylene adipate-co-terephthalate) (PBAT) products. In this work, corn starch, glycerol, initiator bis(1-(tert-butylperoxy)-1-methylethyl)-benzene and crosslinker 1,3,5-tri-2-propenyl-1,3,5-triazine-2,4,6(1H,3H,5H)-trione (TAIC) were first mixed and extruded into crosslinkable thermoplastic starch (TPS). Then, TPS and PBAT were melt-blended to prepare PBAT/TPS composites. Finally, the PBAT/TPS composites were blow molded into films. The effects of different TAIC contents on the degree of gelation, morphological structure, and properties of the composite films were explored. The results showed that TAIC as a crosslinking agent could improve the mechanical properties of the composite films and increase the compatibility of TPS and PBAT. When the content of TAIC was 2 wt % of TPS, and the TPS content was 30 wt %, the composite film exhibited a tensile strength of 25.43 MPa and elongation at break of 580.83%, along with good processing and degradation properties. The significant improvement in mechanical properties was primarily attributed to TAIC crosslinking the TPS and co-crosslinking the TPS and PBAT interface, enhancing their compatibility. The dynamic vulcanization process provided a simple yet effective approach to prepare inexpensive biodegradable composite films with excellent mechanical properties.

Otilionium bromide (OB) is a quaternary ammonium compound which is commonly known in pharmaceutical industry. It affects the distal gastrointestinal tract as an antispasmodic agent which is used by patients with irritable bowel syndrome (IBS). The drug's action is based on the inhibition of L-type and T-type calcium channels. Around 15% of the Western population struggles with IBS. OB is characterized by weak systematic absorption, which may prevent other negative impact on organism. There have been several successful treatments worldwide using OB and placebo. These medical trials have proven to be safe and successful in patients with irritable bowel syndrome. The medication reduces abdominal pain, boiling sensation and relieves discomfort better than placebo. The effects of using OB are longlasing, even after dosing is stopped. Studies have shown that treatment with OB bromide improves quality of life. This article describes the mechanism of action, synthesis, pharmacological effects of OB and aspects in which OB improves a person's quality of life.
