Synthetic Marble. Synthetic marble-like resin products are prepared by casting or molding a highly filled monomer mixture or monomer—polymer symp. When only one smooth surface is required, a continuous casting process using only one endless stainless steel belt can be used (52,53). Typically on the order of 60 wt % inorganic filler is used. The inorganic fillers, such as aluminum hydroxide, calcium carbonate, etc, are selected on the basis of cost, and such properties as the translucence, chemical and water resistance, and ease of subsequent fabrication (54,55). 

The second largest use at 21% is for unsaturated polyester resins, which are the products of polycondensation reactions between molar equivalents of certain dicarboxyhc acids or thek anhydrides and glycols. One component, usually the diacid or anhydride, must be unsaturated. A vinyl monomer, usually styrene, is a diluent which later serves to fully cross-link the unsaturated portion of the polycondensate when a catalyst, usually a peroxide, is added. The diacids or anhydrides are usually phthahc anhydride, isophthahc acid, and maleic anhydride. Maleic anhydride provides the unsaturated bonds. The exact composition is adjusted to obtain the requked performance. Resins based on phthahc anhydride are used in boat hulls, tubs and spas, constmction, and synthetic marble surfaces. In most cases, the resins contain mineral or glass fibers that provide the requked stmctural strength. The market for the resins tends to be cychcal because products made from them sell far better in good economic times (see Polyesters,unsaturated).

Applications. Phthalic anhydride is used largely to make plasticizer for polyvinyl chloride. It is also a feed for alkyd resins and. for unsaturated polyesters that are widely used in construction, rharine, and synthetic marble applications. Other minor applications are dyes, esters, drying oil modifiers and pharmaceutical intermediates.

Synthetic Marble. Highly filled monomer or monomer-polymer syrup mixtures are used to form synthetic marble materials. A single belt approach can be employed in the formation of synthetic marble with only one smooth side (57,58). Aluminum oxide, calcium carbonate, titanium dioxide, etc, are used at loading levels of 60% the specific materials of choice are determined according to the translucence, chemical-resistance, and water-resistance properties desired (59,60). 

Ot h6r. Synthetic marble fixtures and bathtubs are made using methacrylic ester polymers (145,146). Opaque and clear methacrylate sheets have been used as structural components in the manufacture of recreational vehicles (147). These materials are additionally used for electrical insulation. Thermoplastic methacrylate resins are used in lacquer coatings for plastics, in printing inks, as heat seal lacquers for packaging, as screen printing media for decorative porcelain, in traffic paints, and for the protection of buildings from acid rain and weathering (148). Other copolymer used are discussed in the article Ester Polymers.
