Abstract:

The AB2 monomer was prepared by trimellitic anhydride (TMA) and ethylene glycol.The syntheses of hyperbranched polymer based upon TMA as a core molecule and AB2 monomer which contains two single carboxylic group and one hydroxy groups were studied. Two types of hyperbranched polyester (G1,G2) with different relative molecular weight were obtained by reaction between TMA and AB2 monomer and reaction between G1 and TMA respectively with different mole ratio. Using phase transfer catalyst between epichlorohydrin and potash salt hyperbranched polymer, hyperbranched epoxy polymer of G1′ and G2′ was synthesized. The structure of products was characterized by using IR, GPC and 1HNMR. The results show that G1 and G2 have narrow relative molecular weight distribution with 1.008 1 and 1.011 0 respectively; the IR shows that the hyperbranched epoxy polymer is formed.
