ABSTRACT OF THE DISCLOSURE The invention as disclosed provides compositions comprising a film-forming polymer dissolved in an organic solvent, said film-forming polymer containing reactive functionality which is either ethylenic unsaturation or is other than ethylenic unsaturation, and insoluble reinforcing particles, dispersed in said solution which are the reaction product of a system comprising (a) a polyethylenically unsaturated monomer, (b) a portion of said film-forming polymer and, when said reactive functionality is other than ethylenic unsaturation, (c) a linking monomer which contains both ethylenic unsaturation and a group reactive with said reactive functionality. These compositions are useful for films, coatings, caulks, adhesives and mastics having advantageous properties such as low surface tack , short drying time, high tensile strength, and high film hardness.
