Prepolymers with imidegroups and the way of their preparation, for use in making resins curable by ionizing rays.

摘要

These prepolymers originate from the reaction in a homogeneous liquid medium at a temperature of 50 to 250 DEG C, on the one hand, of reactants generating imide groups, consisting of at least two particular maleimides of different kinds and, on the other hand, of two additional reactants, one consisting of a particular acrylate reactant and the other of a particular vinyl compound other than an acrylate. <IMAGE>
