Bulk mouldable compositions containing powdered mineral fillers, short glass fibres, an ethylenically unsaturated monomer and a curable polymer phase which is the reaction product of at least one unsaturated polyester resin, and an organic polyisocyanate. The curable polymer phase in said compositions is the reaction product of at least one unsaturated polyester resin, at least one organic polyisocyanate and at least one hydroxylated (alk)acrylate. Application in the production of moulded parts having improved microscopic appearance and mechanical properties. |
