摘要：
The invention relates to a curable composition comprising: at least one benzoxazine and at least one toughening additive which can be bound to the at least one benzoxazine in the curing process, characterized in that the toughening additive is distributed in the cured composition in form of discrete domains, and that at least 50% of the discrete domains related to the total amount of discrete domains have a maximum length in any direction of space in the range of 10 nm to 500 nm as determined by transmission electron microscopy (TEM).
