The invention pertains to (meth)acrylate-based reactive diluent compositions enabling styrene-free curing of unsaturated polyester resins. The reactive diluent compositions comprise a (meth)acrylic acid ester monomer and a compatibilizing agent including at least one (meth)acrylate moiety and at least one additional ethylenically unsaturated moiety. L'invention concerne des compositions de diluant réactif à base de (méth)acrylate permettant le durcissement sans styrène de résines polyester insaturées. Les compositions de diluant réactif comprennent un monomère d'ester d'acide (méth)acrylique et un agent de compatibilisation comprenant au moins une fraction (méth)acrylate et au moins une fraction supplémentaire à insaturation éthylénique.
