Poly(ethylene glycol)-poly(vinyl alcohol)-adamantanate: synthesis and stimuli-responsive micelle properties†
Abstract
A pH-sensitive amphiphilic polymer based on poly(vinyl alcohol) (PVA), modified with poly(ethylene glycol) (PEG) and adamantane (Ad) pendant groups, has been synthesized and the self-assembly properties of this PEG-PVA-Ad construct investigated. PEG-PVA-Ad polymer forms micelles via self-assembly at concentrations as low as 26 mg L−1. These polymer micelles can be destroyed by low pH or the addition of β-CD.
