Abstract
A bisimide-ether compound having the general formula is obtained by reacting an ethylenically unsaturated dicarboxylic acid anhydride, a diamine compound and a phenolic compound having in the molecule at least two hydroxyl groups, or by reacting a prepolymer of the anhydride and diamine compound with the phenolic compound: ##STR1## wherein R.sub.1 is a group containing at least two carbon atoms, R.sub.2 is a group containing at least two carbon atoms, R'.sub.2 is a group containing at least two carbon atoms and a carbon-carbon double bond, R.sub.3 is an aromatic group, the nitrogen atoms of the imide rings being directly connected to different carbon atoms of the group R.sub.1, the carbonyl groups of the imide rings being directly connected to different carbon atoms of the group R.sub.2 or R'.sub.2, the oxygen atoms between the groups R.sub.2 and R.sub.3 being directly connected to an aromatic nucleus of the group R.sub.3, and n is an integer of zero, one or more than 1.
