Summary:1. Field of the Invention A procedure for the production of a modified acrylic sheet with high impact resistance, of the type in which a prepolymerization is done of a mix of monomers with a polymer of dissolved dienic monomers. The procedure is done in batches at low temperatures without there being a separation of the polymer of dienic monomers from the rest of the mix. The procedure facilitates obtaining a modified acrylic sheet with high impact resistance whose transmittance is kept after being subjected to an accelerated degradation, and whose impact properties are not reduced more than 50% after said accelerated degradation.
