The present invention relates to a precursor composition for (meth) acrylic thermoplastic composites, its method of preparation and its use. In particular it relates to a semi-fabricated composition comprising a (meth) acrylic polymer, a monomer, a fibrous material and at least one initiator. More particularly the present invention relates to a precursor composition comprising a (meth) acrylic polymer, a monomer, a fibrous material and at least two initiators. The present invention relates also to a method of preparation of a composition comprising a (meth) acrylic polymer, a monomer, a fibrous material and at least two initiators.

A system and method of forming a coated substrate are provided. A substrate is provided that has a polymeric surface and a lower, initial surface energy. A corona discharge treatment is applied to the polymeric surface. The application of the corona discharge treatment results in a surface energy that is greater than the initial surface energy. A composition having one or more 1,1-disubstituted alkene compounds is deposited directly on the corona treated surface and in direct communication with the surface to provide a coating, eliminating the use of an adhesion promoter.

A coating composition for a food or beverage can that includes an emulsion polymerized latex polymer formed by combining an ethylenically unsaturated monomer component with an aqueous dispersion of a water-dispersible polymer.

Disclosed are hollow polymer spheres prepared from one or more hydrophilic ethylenically unsaturated monomers containing acid functionality, one or more nonionic hydrophilic ethylenically unsaturated monomers, and one or more hydrophobic ethylenically unsaturated monomers. Disclosed is a process for preparing such hollow spheres. The hollow spheres exhibit controlled particle size, which can have larger particle sizes, narrow particle size distributions and high void volume percentages.
