Improvement of mechanical properties and heat distortion temperature of polylactic acid by highly aromatic hyperbranched polyamide was written by Sun, Jianjian;Huang, Yansong;Jin, Yujuan;Tian, Huafeng;Men, Shuang. And the article was included in Journal of Applied Polymer Science in 2022.HPLC of Formula: 4422-95-1 This article mentions the following:
The highly aromatic hyperbranched polyamide (HBPA) was synthesized and used as a modifier in order to enhance the phys. performance of polylactic acid (PLA). The results showed that compared to the neat PLA, the tensile strength of the PLA/HBPA blends increased by 41.8%; fracture energy increased by 42.8% when the content of HBPA was 1.0 phr. The addition of HBPA can significantly improve the thermal deformation temperature of PLA. The polarized optical microscope images suggested that HBPA can act as a nucleating agent for PLA during the isothermal crystallization This research indicated HBPA exhibits excellent reinforcing effect for PLA, due to the formation of hydrogen bonds and/or chem. crosslinking between HBPA and PLA. In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1HPLC of Formula: 4422-95-1).
Trimesoylchloride (cas: 4422-95-1) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.HPLC of Formula: 4422-95-1
