Emulsion Polymerization of Vinyl Monomers in Presence of Chitosan with Peroxide Groups

Peroxychitosans with ditertiary peroxide fragments were synthesized via radical reactions of chitosan and 5-tert-butylperoxy-5-methyl-l-hexen-3-in. They can be used as macroinitiators and coemulsifiers for emulsion polymerization of vinyl monomers. It is shown that peroxychitosans are grafted to the surface of latex particles and impart antibacterial properties to emulsion polymer.
