Preparation and characterization of narrow compositional distribution polyampholytes as potential biomaterials: Copolymers of N‐(3‐aminopropyl)methacrylamide hydrochloride (APM) and methacrylic acid (MAA)

ABSTRACT This article describes the preparation and solution properties of a series of polyampholytes composed of N ‐(3‐aminopropyl)methacrylamide hydrochloride (APM) and methacrylic acid (MAA). In particular, conditions were found where the copolymers could be formed with little or no drift in composition over the course of polymerization to quite high conversions. The compositional drift, common to many copolymerizations, was limited by …
