Abstract
A method of making acrylic products having a relatively even distribution of visible accent particles dispersed therein. The acrylic products are made from a composition comprising an acrylic matrix comprising a monomer rich syrup and having pre-formed particles added thereto. The pre-formed particles are evenly dispersed in the matrix by virtue of their geometry, similarity in composition or specific gravity to that of the matrix. When added with the accent particles, the pre-formed particles serve the function of restricting the movement of, and thereby suspending the accent particles in an even dispersion within the matrix. The results is an even distribution of the accent particles in the finished product.
