On June 22, 2022, Zhou, Jiajun; Li, Mao; Wu, Jiadong; Zhang, Chongyin; He, Zidong; Xiao, Yan; Tong, Gangsheng; Zhu, Xinyuan published an article.SDS of cas: 574-98-1 The title of the article was One-pot synthesis of hydroxyl terminated hyperbranched semi-aromatic Poly(ester-imide)s. And the article contained the following:
A new kind of hyperbranched semi-aromatic poly(ester-imide)s with hydroxyl terminated groups has been prepared from com. available 1,2,4-benzenetricarboxylic anhydride (TMA) as the AA’-type aromatic monomer and 3-amino-1,2-propanediol (3APPD), 2-amino-1,3-propanediol (2APPD), N,N-bis(2-hydroxyethyl)ethylenediamine (BHED) as CB2-type aliphatic monomers via a simple one-pot melting polymerization method. The effects of synthesis conditions on the structures and properties of the products were investigated in detail. The combination of FTIR, 1H NMR, 2D NMR, MALDI-FTICR-MS and model reactions have been used to characterize the structures of the obtained polymers. As assessed using thermal measurements, the obtained hyperbranched semi-aromatic poly(ester-imide)s possess low glass transition temperature (≤120°C) and high thermostability with an onset decomposition temperature ranging from 355 to 420°C in nitrogen. The products possess abundant terminal hydroxyl functional groups. Hydroxyl values vary between 198 and 248 mg KOH/g depending on the particular precursors used to generate the polymers. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).SDS of cas: 574-98-1
