A polymer composite comprising a hydroxy-phenoxyether or hydroxy-phenoxy ester polymer matrix and an inorganic filler is prepared by melt-blending the polymer and the inorganic filler. The filler may be an inorganic metal oxide, metal hydroxide, metal carbonate, metal nitride, metal carbide or metal boride. Methods of polymer composite preparation involving in situ type polymerization may also be used. The polymer composites have increased barrier capabilities compared to the unmodified polymers.

L'invention concerne un composite polymère comprenant une matrice polymère d'hydroxy-phénoxyéther ou d'hydroxy-phénoxyester et une charge inorganique préparée par mélange par fusion du polymère et de la charge inorganique. La charge peut être un oxyde métallique, un hydroxyde métallique, un carbonate métallique, un nitrure métallique, un carbure métallique ou un borure métallique. L'invention concerne également des procédés de préparation du polymère composite impliquant une polymérisation de type in situ. Le polymère composite possède des propriétés de barrière par rapport aux polymères non modifiés.
