ABSTRACT:
A mixture consisting of a polymaleimide and a copolymerizable monomer or a prepolymer formed from these two compounds contains, as the polymerization catalyst, an ethane which is substituted by aromatic groups and hydroxyl groups or halogen (cf. formula II), such as benzpinacol. The mixture is stable on storage and heat-curable. It can be cured, while at the same time being shaped to give mouldings, sheet-like structures, laminates, adhesive bonds or foams, for example by casting or compression moulding.
