Heat-curable biobased casting composition, shaped article produced therefrom and process for producing such a shaped article

A heat-curable biobased casting composition, comprising

• (a) a mixture of two or more monofunctional acrylic and/or methacrylic monomers, wherein one or more monomers are derived from recycled material and one or more monomers are plant-based or of animal origin,
• (b) one or more polyfunctional acrylic and/or methacrylic biomonomers that are plant-based or of animal origin,
• (c) one or more polymers or copolymers selected from polyacrylates, polymethacrylates, polyols, polyesters derived from recycled material or plant-based or of animal origin,
• (d) inorganic filler particles of natural origin, wherein the proportion of the monofunctional acrylic and/or methacrylic monomers and of the polyfunctional acrylic and methacrylic biomonomers is 10-40% by weight, the proportion of the polymer (s) or copolymer (s) is 1-16% by weight and the proportion of the inorganic filler particles is 44-89% by weight, and wherein at least the non-recycled monomers, biomonomers, polymers or copolymers are non-petrochemically based.
