ABSTRACT:
The invention relates to the manufacture of crosslinked polymers which contain imide groups by reacting polymaleimides with alkenylphenols or alkenylphenol ethers, preferably at temperatures of 100.degree. to 250.degree. C. The reaction mixture optionally also contains polymerization catalysts. The manufacture of the polymers is as a rule carried out with simultaneous shaping. Shaped articles (for example castings), laminates, adhesive bonds and foams can be manufactured in this way. It is also possible to carry out the reaction in solution.
