    Abstract: The invention relates to a process for preparing a material consisting of a PVC matrix reinforced with clay comprising the following successive stages: (1)) preparation of a modified clay by mixing a natural clay with a non-volatile solvating compound, the mixture being carried out by applying at least one of the following mechanical stresses: compression, at a speed of between 0.01 and 0.05 m/s; shear, at a speed of between 0.05 and 5 m/s; friction, at a speed of between 0.05 and 5 m/s; attrition, at a speed of between 2 and 4 m/s; (2) incorporation of the modified clay into the PVC by mixing in the molten state, the implementing conditions being such that: the speed of compression is between 0.1 and 5 m/s; the speed of shear is between 0.05 and 5 m/s.
