Abstract
A process for detecting the sensitivity of one or more polymers and/or of one or more, mixtures of polymers to a compound, including the steps of exposing at least one lens-shaped micro-deposit, including the polymer(s) and/or the mixture(s) of polymers, to the compound, and detecting, by illuminating the surface of this micro-deposit, a change in the spatial distribution of the intensity of the light reflected or transmitted by this micro-deposit, linked to a variation in the dimensions and/or refractive index of this micro-deposit, under the effect of an interaction between the polymer(s) and/or the mixture(s) of polymers and the compound.
