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 deleterious gases.
一类相对低分子量的低聚物,含有至少一个异亚胺基团和能够发生加成聚合反应的末端基团。 本发明低聚物的特点是在普通溶剂中具有极佳的溶解性,熔化温度大大低于其固化温度,从而使低聚物能够在更低的温度下更慢地形成固化聚合物,且不会产生有害气体。
