Polyester tere- & isophthalic acids
WebBranched polyesters based on the polyethylene terephthalate were synthesized by incorporating isophthalic acid (IPA) and trimellitic anhydride (TMA). TMA has the branching agent role. During the esterification step, only terephthalic acid, IPA, and ethylene glycol were reacted and TMA was added at the beginning of the polycondensation step. WebJul 30, 2024 · Phthalic acid and isophthalic acid are isomers of each other. The molecular chains of unsaturated polyester synthesized from them are o-phthalic and isophthalic, respectively.
