Abstract
Specific bismaleimide compounds are made, and curable compositions are made that include at least one of these bismaleimides and at least one specific polyimide. A process is developed for the manufacture of these curable compositions, and crosslinked polymers are obtainable by this process. A process is developed for the manufacture of a composite material by curing a mixture of a fibrous or particulate reinforcement and the curable composition or the crosslinked polymer as well as the obtained composite material.
