ABSTRACT:
According to the invention, polyaddition products containing imide groups are manufactured by reacting certain polyimides (preferably maleimides) with polyhydric alcohols in the presence of basic compounds. The preferred embodiment (E) relates to the use of catalysts as basic compounds. In particular, amines and alkali metal compounds can be used. A further embodiment (F) relates to the use of primary polyamines as basic compounds. In the latter case, the polyamine participates in the polyaddition mechanism, that is to say the molecules are incorporated into the polyaddition products. In this latter case, catalysts can also be used additionally.
