Recent advances in cationic photopolymerization

Abstract

The paper reports important strategies to overcome limitation of cationic photopolymerization. First, it was possible to run emulsion cationic photopolymerization in water, taking the advantages of hydrophobic droplets of suitable dimension to avoid termination reaction, achieving capsules of about 200 nm. Subsequently a frontal polymerization reaction is used to promote the UV-induced crosslinking process of an epoxy composites via a radical induced cationic frontal polymerization.
