| Abstract: | A method for the holographic determination of the chemical kinetic order of irradiance in linear-chain polymerization rates
using phase gratings recorded over dry photopolymer films is derived. This method, based in the initial slope of the recorded
diffraction efficiency, does not depend on any model of the grating growth, and it allows to collect information on the kinetic
mechanisms involved in the polymerization. An acrylamide-based linear-chain photopolymer is analysed.
