| abstract |
Artificial marble or granite having excellent aesthetic properties, patterns and tonalities which cannot be found in natural materials are prepared from a composition containing a polymerizable poly(allyl carbonate) of a polyol and mineral filler, where the mineral filler is a carbonate type in the case of marble, and silicate or silica type in the case of granite, and is in the form of particles of which at least 40% to 100% by weight have a particle size greater than 0.5 mm. The artificial marble and granite produced by the process of the invention require a limited quantity of polymerizable poly(allyl carbonate) binder, have excellent aesthetic properties and high aging resistance, making them suitable for external use. |
