Patent number: 6734230Abstract: 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.Type: GrantFiled: July 8, 2002Date of Patent: May 11, 2004Assignee: Plastiglas de Mexico, S.A. de C.V.Inventors: Sergio Colin Escobar, Manuel Ahumada Romero, José Luis Pe{overscore (n)}a Rosas, Maria Sonia Limon Rodriguez, Luis Enrique Mille Loera, Leopoldo Vilchis Ramirez
