Abstract (en)

[origin: WO2007057525A1] The invention relates to a method for protecting a plastic structure consisting in superimposing by coextrusion, hot compression and by multiple injections a PMMA-containing protective layer (I), possibly a pigmented layer (II) and an intermediate ductile layer (III) comprising a sequence copolymer of formula BA<SUB>n</SUB> consisting of a block polymer B comprising at least 60 % by weight of at least one type of (meth)acrylic monomer whose T<SUB>g</SUB> is less than 5 °C, n blocks of polymer A which are bound to the polymer B block by covalent bonds, wherein n is an integer ranging from 1 to 10, and comprise at least 60 % by weight of at least one type of (meth)acrylic monomer whose T<SUB>g</SUB> is greater than 0 °C, and a structured plastic layer (IV).
