(Metha)acrylic composition, foam material obtained from such a composition, process for producing said composition and said foam, and their uses

Abstract

(Method)acrylic composition, foam material obtained from such a composition, process for producing said composition and said foam, and their uses. The present invention relates to a (meth)acrylic composition suitable for preparing a (meth)acrylic foam, a process for preparing the (meth)acrylic composition and the (meth)acrylic foam, and also a foam material obtained by polymerization of such a (meth)acrylic composition.In particular, the present invention relates to a (meth)acrylic composition suitable for preparing a (meth)acrylic foam, said (meth)acrylic composition comprising a polymerizable liquid (meth)acrylic syrup, a blowing agent, and an initiation system for starting the polymerization of said composition, a method for preparing the (meth)acrylic composition and the (meth)acrylic foam, and also a foam material obtained by polymerizing such a (meth)acrylic composition. The invention also relates to a (meth)acrylic composite material comprising a cavity filled with the (meth)acrylic foam, a method for preparing such a (meth)acrylic composite material comprising a cavity filled with the (meth)acrylic foam, and an object comprising such a (meth)acrylic composite material including a cavity filled with the (meth)acrylic foam.
