HEAT-CURABLE BIOBASED CASTING COMPOSITION, SHAPED ARTICLE PRODUCED THEREFROM AND PROCESS FOR PRODUCING SUCH A SHAPED ARTICLE

摘要

A heat-curable biobased casting composition, including(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 of vegetable or animal origin,(b) one or more polyfunctional acrylic and/or methacrylic biomonomers of vegetable or animal origin,(c) one or more polymers or copolymers selected from polyacrylates, polymethacrylates, polyols, polyesters derived from recycled material or of vegetable or 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.
