PROCEDURE FOR THE OBTAINMENT OF MODIFIED ACRYLIC SHEETS OF HIGH IMPACT RESISTANCE

摘要

The invention relates to a method for obtaining a modified high impact resistant acrylic sheet by prepolymerizing a monomer mix with a diluted dienic monomeric polymer, which is carried out in batches at low temperatures without separating the dienic monomeric polymer from the rest of the mix. The method disclosed in the invention makes it possible to obtain a modified high impact resistant acrylic sheet whose transmittance is maintained after being subjected to accelerated degradation and whose impact resistance properties are preserved by more than 50 % after said accelerated degradation.
