ABSTRACT:
Filled plastic molded articles based on polymethyl methacrylate (PMMA), which articles resemble granite, are prepared by preparing a casting resin suspension comprising: (A) 20-80 parts by wt. (pbw) of a liquid PMMA polymer precursor; (B) 0-75 pbw of a non-metallized particulate filler; (C) 0-5 pbw, based on the sum of components (A) and (B) of a polymerizable organosilicon compound; and (D) 0-2 wt. % of at least one pigment or colorant; suspending metallic appearing particles of a platelet-like stratified silicate (SS) in the particle size range of 20-500 .mu.m in an amount of 1-35 pbw, based on the sum of components (A) and (B); polymerizing the suspension under free radical conditions in a polymerization mold; and removing the polymerized article from the mold.
