ABSTRACT:
Thermosetting esterimide oligomers of formulas (IA) and (IB) are disclosed: ##STR1## where A.sub.1, A.sub.2 and A.sub.4 are divalent organic groups, A.sub.3 is a monovalent organic group and A.sub.1, A.sub.2, A.sub.3 and A.sub.4 may be the same or different, with m being an integer of 1-30. The above compounds provide hard substances having excellent workability, heat resistance and mechanical properties.
