Abstract: Embodiments relate to a (meth)acrylic composition and also to a composite material obtained by polymerization of such a (meth)acrylic composition. Embodiments may relate to a (meth)acrylic composition comprising also a block copolymer, preferably a (meth)acrylic block copolymer and also to a composite material obtained by polymerization of such a (meth)acrylic composition comprising a block copolymer, preferably a (meth)acrylic block copolymer. Embodiments may relate to a (meth)acrylic composition comprising also a (meth)acrylic block copolymer and a mineral filler as well to a composite material obtained by polymerization of such a (meth)acrylic composition comprising a (meth)acrylic block copolymer and a mineral filler. Embodiments may relate to a manufacturing process of a (meth)acrylic composition comprising a (meth)acrylic block copolymer and a mineral filler, manufacturing process of composite material obtained by polymerization of such a (meth)acrylic composition and also to the uses of such a (meth)acrylic composition and obtained composite material.

Abstract: Provided is a composition including a polymer matrix having an elastomer phase with a glass transition temperature of less than or equal to 20° C. and particles of cork which are dispersed in the polymer matrix. Also provided is a process for preparing the composition by hot-mixing the polymer matrix in a softened state with the particles of cork and optionally with one or more additives, in an extruder, the particles of cork being introduced laterally after the introduction of the polymer matrix which is introduced into the feeder at the beginning of extrusion.
