ABSTRACT:
A class of relatively low molecular-weight oligomers containing at least one isoimide group and terminal groups capable of undergoing an addition polymerization reaction. The oligomers of the present invention are characterized by excellent solubility in common solvents and a melting temperature considerably lower than their cure temperature, thus enabling the oligomers to be formed into cured polymers more slowly and at lower temperatures, all without the evolution of deletrious gases.
