Claim Text:
1. A transparent and impact-resistant crosslinked acrylic composition comprising: a brittle matrix (I) having a glass transition temperature of greater than 0° C., elastomeric domains having a characteristic dimension of less than 100 nm consisting of from 5 and 20% by weight macromolecular sequences (11) having a flexible nature with a glass transition temperature of less than 0° C., characterized by a number-average molecular weight of between 30,000 and 500,000 g/mol, and between 0.1 and 2% by weight of a crosslinking agent, with respect to the crosslinked polymer material, wherein said crosslinking agent is selected from the group consisting of one 1,4-butylene glycol dimethacrylate, and 1,3-butylene glycol dimethacrylate, and mixtures thereof, wherein said macromolecular sequence does not contain any diene.
