Inhibition of Premature Polymerization of Cationically Polymerizable Low Viscosity Systeme

Popis výsledku v původním jazyce

Photocurable inkjet inks based on cationically curable materials are a promising new technology with many advantages and some problems yet to be solved. One of the latter is the long-term stability of liquid inks. Reactive monomers are stable in the darkat room temperature for a long time. When a photoinitiator (iodonium salt) is added, premature gelation takes place within several days, depending on the temperature. Tertiary amine, hindered amine, hindered phenol, a quinone derivative, a sulphur-basedantioxidant, beta-carotene and their selected mixtures were tested as potential inhibitors of premature cationic polymerization by being subjected to accelerated ageing at higher temperatures. The influence of additives on photoinitiated polymerizationwas studied by means of FTIR spectroscopy. The inhibition effect of additives was ascertained by monitoring the changes in viscosity during long-term temperature exposition as well.
