synthetic stone composition, kit, methods for the manufacture and production of synthetic stone, synthetic stone, and use of a composition or kit.

摘要

A composition for synthetic stone is described. the composition having (a) 3 to 25 wt% acrylic resin, the acrylic resin having: - (i) 50 to 95 wt% methyl methacrylate and methyl methacrylate monomer residues, (ii) 4 to 40% by weight of higher boiling mono (alk) acrylate monomer, (iii) optionally 0 to 10% by weight of other acrylate or vinyl comonomer residues and (iv) a crosslinking agent. The mma residues of component (a) (i) are present in the acrylic resin as a (co) polymer containing mma residue comprising at least 80% by weight of the (co) polymer mma. the composition further having (b) 70 to 95% by weight of filler; and (c) optionally a coupling agent. the composition being especially useful for the manufacture of synthetic stone for use in outdoor applications.
