   Abstract : This thesis deals with the photopolymerization of mono-, di- and trifunctional monomers initiated by carnphorquinone (CQ) alone and/or with different amines (AMH) as coinitiators in air as well in nitrogen. The kinetics of photopolymerization was measured by photoisothermal calorimetry (photo-DSC), which allowed the measurement of the rate of polymerization (Rp), maximum rate of polymerization (Rpmax), time of inhibition (tinh), time at which Rpmax was obtained (tmax), double bond conversion (p) and maximum double bond conversion (pmax).
