Synthesis, thiol-yne 'click' photopolymerisation and physical properties of networks derived from novel multifunctional alkynes

摘要

The thiol-ene photopolymerisation has many benefits including almost complete conversion, fast polymerisation, in the presence of air or water and without the need for a photoinitiator. Thiol-yne reactions have many of the same benefits. In a two step process each alkyne reacts with two thiol groups with the initial vinyl sulphide intermediate being approximately 3 times more reactive than the alkyne toward thiol addition.
