A
novel terminal modification agent to endow hyperbranched polyamidoamine
(HPAMAM) with thermo-/pH-responsive properties is reported. HPAMAM with
terminal vinyl groups is first synthesized and then end-capped by
1-adamantylamine (ADA). The resulting hyperbranched polymer (HPAMAM-ADA)
shows interesting thermo-responsive properties in aqueous solution,
which have been investigated by UV-vis spectroscopy, optical microscopy,
and 1H NMR spectroscopy. The lower critical solution
temperature can be controlled by adjusting the end-capping ratio of ADA.
In addition, HPAMAM-ADA exhibits a pH-dependent water solubility. This
pH-responsive behavior is also studied.
