Polymerisation of acrylic oligomers photoinitiated by XeCI laser radiation

Polymerisation of OKM-2 and TGM-3 films was photoinitiated by pulse-periodic XeCI laser radiation (λ = 308 nm). The radiation-dose dependences of the mass and thickness of hardened films, and of the degree of conversion of double bonds were determined for polymerisation both in air and in an inert gas. A study was made of the influence of the energy density of laser pulses on the polymer yield. The changes in the transmission spectra of the irradiated films were studied. The energy expenditure in the hardening of the films depended strongly on the energy density of the laser pulses. The parameters of the polymerisation kinetics were estimated.
