Photoinitiated Polymerization of Selected Thiol-ene Systems

摘要

Thiol-ene based photocurable systems exhibit very rapid rates of polymerization in nitrogen that are comparable to those achieved with traditional nitrogen saturated acrylates. In the presence of air, rates of thiol-ene copolymerization are much greater than are attained by traditional multifunctional acrylates. Even in the absence of an added photoinitiator, rapid copolymerization (thiol-acrylate) and homopolymerization (acrylate) rates of a multifunctional thiol and a difunctional acrylate are recorded in air.
