Solution Properties of Polyvinylamine Derivatized with Phenylboronic Acid
Abstract
The phase behavior and surface tension of aqueous, linear polyvinylamine (PVAm) bearing pendant phenylboronic acid moieties (PBA) were measured as functions of pH and the degree of PBA substitution. Coupling of PBA with 4% of the nitrogen on low molecular weight (15 kDa) PVAm gave water-soluble copolymer from pH 1 to 12. By contrast, derivatives of 150 kDa PVAm phased separated at pH 9 with as little as 4% derivatization. The pH ranges over …
