Abstract
A method for producing synthetic shaped articles simulating marble, granite or the like is provided by the present invention. A thermosetting resin is subjected to first reaction conditions effective to partially polymerize the resin to form a semi-solid mass. The partially polymerized semi-solid mass of resin is comminuted to form a plurality of discrete partially polymerized resin particles. An article of the desired shape is formed from a mass of the partially polymerized resin particles. The thus formed shaped article is then subjected to second chemical reaction conditions effective to polymerize the resin to provide a synthetic shaped article simulating marble, granite and the like.
