Method of preparation of plates run in LDC reinforced with the impact using a copolymer àbloc B (- A) N made up of a heart B and N branches has including/understanding the following stages : 1. to prepare the heart B while mixing with (X) monomeric (S) intended (S) to form the heart B a alcoxyaminede general formula Z (- T) N in which Z indicates a grouping multivalent, T a nitroxyde and N is unentier equal to or higher than 2; 2. to prepare copolymer with blocks B (- A) N by mixing the heart B obtained at stage 1 to (X) monomeric (S) intended to form the branches has; 3. to mix copolymer with blocks B (- A) N of stage 2 with methyl methacrylate and possibly aumoins a cornonomère M and with at least a ridicalizing igniter; 4. to run the mixture obtained at stage 3 in a mould, then to heat it to obtain a cast plate. |
