Preparation Of Amphiphilic Hyperbranched Poly(amide-ester) And Its Phase-transfer Behavior For Dyes

In this manuscript, hyperbranched poly(amide-ester)(HPAE) with plenty of hydroxylgroups in the end was obtained using AB3monomer which was prepared by condensationreaction between succinic anhydride and tri(hydroxymethyl)-aminomethane under ice-bath.HPAE was further reacted benzoyl chloride to afford a novel amphiphilic polymer (HPAEB)with hydrophiphilic core and hydrophobic shell in the presence of Et3N. The polymers (HPAEand HPAEB) were fully characterized by FT-IR and TGA. Meanwhile, their solubility andthermal properties were also measured. This novel amphiphilic hyperbranched polymer(HPAEB) could transfer some small dyes (such as rose red, methyl orange (MO) and methylblue(MB)) from aqueous phase to organic phase. In addition, the phase transfer behavior forMO and MB was also studied. This manuscript consists of three chapters.In Chapter1,we focused on the introduction of synthesis, properties, application andfurther development of some amphiphlic hyperbranched polymers.In Chapter2, the synthesis and characterization of the amphiphilic hyperbranchedpoly(amide-ester)(HPAEB).In Chapter3: the phase-transfer behavior study of amphilic hyperbranchedpoly(amide-ester) for some dyes.
