Particles having surfaces functionalized with 1,1-di-activated vinyl compounds

A method for improving dispersibility of solid particles in a solvent, a film-forming resin, a plastic, or a combination thereof, the method comprising forming a functionalizing layer over at least a portion of an outer surface of the solid particles, the forming the functionalizing layer comprising:

• forming a bond between at least a portion of the solid particles and a 1,1-di-activated vinyl compound, or a multifunctional form thereof, or a combination thereof, and/or physically and/or chemically absorbing a polymerization reaction product of the 1,1-di-activated vinyl compound, or a multifunctional form thereof, or a combination thereof onto a surface of at least the portion of the solid particles, wherein the dispersibility of the solid particles is improved in comparison to the same solid particles prior to improving the dispersibility of the solid particles and wherein the 1,1-diactivated vinyl compound comprises a methylene dicarbonyl compound.
