摘要：
The paper describes the photopolymerisation process of certain acrylate and methacrylate monomers mono and bifunctionals. The initiation is assured by the silice particles of which surface contains the azo groupments able to be easy decomposed by the UV rays and form free radicals. The influence of certain factors (the working temperature, concentration of the initiator, the monomer nature and the environment) upon the process characteristics (the conversion. the reaction rate, the reaction enthalpy, the peak maximum, the induction time, the percentage of monomer reacted at peak and the rate constant) were studied.
