Claim Text:
1. A moldable engineered stone composition, comprising: (a) 15 to 20% by weight of the composition of a matrix resin comprising a syrup of an unsaturated acrylic polymer containing from 1 to 10% by weight of the polymer of an acrylic carboxylic acid copolymerized with monounsaturated esters and having unreacted acid groups, and from 1 to 5% by weight of the polymer of a crosslinking acrylic monomer, (b) from 80 to 85% by weight of the composition of a mineral particulate, (c) from 0.20 to 5% by weight of the composition of an ionic crosslinking agent, said ionic crosslinking agent forming ionic bonds with said unreacted acid groups, said ionic bonds causing a thickening prior to covalent crosslinking, and (d) a free radical polymerization initiator.
