Abstract: The invention concerns a method for crosslinking a thermoplastic polymer or copolymer with vinyl acetate units, which consists in reacting, during the implementing processes, at a temperature ranging between 80 DEG C and 280 DEG C: the polymer or copolymer with vinyl acetate units, and a polyfunctional alcoholate, in the presence of a catalyst. The crosslinking of polymers or copolymers with vinyl acetate units in the presence of a second thermoplastic polymer or copolymer enables to prepare TPV materials. The method for obtaining a hybrid organic-inorganic material consists in: dispersing and grafting an inorganic network on a thermoplastic polymer or copolymer with vinyl acetate units inducing hydrolysis-condensation of the polyfunctional alcoholate pertaining to the network based on polymer or copolymer with vinyl acetate units and of the excess polyfunctional alcoholate. Said dispersion and said grafting can be carried out in the presence of a second thermoplastic polymer or copolymer for producing hybrid organic-inorganic TPV materials.
