FIELD: chemistry.SUBSTANCE: present invention relates to marble chips for artificial marble, a method for production thereof and artificial marble containing said chips. The marble chips are obtained by hardening a polymer composition containing 50-90 pts.wt binder - halogen-alkoxylated di(meth)acrylate oligomer and 10-50 pts.wt reactive monomers selected from a group of aromatic vinyl monomers, aromatic divinyl monomers, dimers thereof, alkyl- or halogen-substituted aromatic vinyl monomers, C-Calkyl(meth)acrylates, C-Caryl(meth)acrylates, hydroxyl-containing (meth)acrylates, glycidyl(meth)acrylates, C-Carylphthalates, C-Carylcarbonates and combinations thereof. The marble chips enable to obtain a uniform pattern regardless of the duration of hardening or casting.EFFECT: artificial marble made from the marble chips can have an outer appearance and structure similar to the outer appearance and structure of modelled stone, and also have processability during heat treatment and suitability for treatment preferred for artificial marble.21 cl, 2 dwg, 1 tbl |
