<p>Disclosed is a curable composition comprising an unsaturated polyester and an unsaturated monomer copolymerisable with said unsaturated polyester in the presence of polymerisation accelerators and initiators, characterised in that the unsaturated polyester is an epoxidised unsaturated polyester obtainable by reaction between unsaturated polyester obtainable by reaction between the carboxy end groups of a polyester comprising unsaturated monomer units and the epoxy groups of an epoxy resin. Disclosed is also a process for the preparation of agglomerated stones by compacting calcium carbonate or silica powder or chippings with a the curable composition of the invention.</p> |
