The present invention relates to a (meth)acrylic composition suitable for (meth)acrylic polymeric compositions and (meth)acrylic polymeric composites, its method of preparation and its use. In particular the present invention relates to a (meth)acrylic composition that is slightly crosslinked once polymerized and that is suitable for (meth)acrylic composites and more particular for rebars. More particularly the present invention relates to a (meth)acrylic composition suitable for rebars, preparing such a (meth)acrylic compositions, composite rebar comprising is and method of preparing such a composite rebar. The present invention also relates also to the use of such a (meth)acrylic composition and use of rebars.

(Meth) acrylic polymeric compositions for composite, its method of preparation and use

The invention relates to foamed acrylic materials using both traditional chemical blowing agents as well as foamable microspheres. The acrylic foams have improved density reduction, optical properties, and insulation properties. The acrylic foams of the invention can be formed by traditional melt processing methods (extrusion, blow molding, etc.) as well as innovative foaming methods, such as foaming during or after polymerization. One novel method of the invention involves the use of expandable microspheres blended with monomers, the monomers then polymerized through bulk polymerization in cell cast, infusion, or compression molding processes. This method can be effectively used to produce composite foam structures, such as in combination with ELIUM® liquid resins from Arkema.

Foamable acrylic composition

A curable composition containing at least one of a haloalkyl ether (meth)acrylate or a haloalkenyl ether (meth)acrylate and, optionally, one or more different types of co-monomers is cured to provide a polymer having advantageous properties as a result of the incorporation of halogenated functionality derived from the haloalkyl/haloalkenyl ether (meth)acrylate monomer.
