Beschreibung

Allgemeine Beschreibung

[2-(Methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (DMAPS) is a hygroscopic, zwitterionic monomer used in the synthesis of polysulfobetaines. Polysulfobetaines are electrically neutral polymers that contain both cationic and anionic groups within a single monomer unit and feature interesting properties such as antielectrolyte behavior in aqueous salt solutions, biocompatibility, and hemocompatibility. Based upon these properties, polysulfobetaines are useful in many biomedical applications such as drug delivery and drug formulation.

Anwendung

Due to its hygroscopic nature, [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (DMAPS) can contain up to one molecule of water per monomer unit. This material should be stored in a cool, dry place and depending on the reaction conditions, water may need to be removed prior to polymerization.
