Search for dual-initiator synergy in UV-initiated acrylate-epoxy hybrid polymerization systems

摘要

Hybrid photopolymerisations of acrylate/epoxide mixtures are less sensitive to oxygen and moisture than their respective neat systems. However, the acrylate polymerisation is significandy faster than the epoxide polymerisation and tends to suppress the epoxide conversion level. One method of increasing the conversion and rate of polymerisation of both systems is to introduce a radical species that can be oxidised to a carbon-based cation (called free radical promoted cationic polymerisation (FRPCP)).
