Abstract
The present invention relates to a composition comprising at least one (meth)acrylic monomer, optionally at least one (meth)acrylic polymer and at least one organic peroxide chosen from hemiperoxyacetals. The invention also relates to the use of said at least one organic peroxide for the polymerization of a composition comprising at least one acrylic monomer and optionally at least one acrylic polymer, to the use of the composition of the invention for the manufacture of resins, to a process for manufacturing thermoplastic, thermoset or composite parts, and also to the parts obtained themselves.
