    • Curable bisimide compositions containing at least one biscitraconimide having general formula (I), wherein D is a divalent group, R is CH2-R1, and R1 is independently selected from hydrogen and alkyl groups having 1-18 carbon atoms; at least one olefinically unsaturated material, and 0-15 mole percent, based on biscitraconimide of formula (I), of a cocurable material selected from the group consisting of bismaleimides, citraconic maleimides and itaconic maleimides, wherein the mole ratio of biscitraconimide of formula (I), to olefinically unsaturated materials is from 0.12 to 4.0; are disclosed. Also disclosed are copolymeric compositions of biscitraconimides and olefinically unsaturated materials, processes for making these copolymers and articles of manufacture embodying these copolymers. These copolymers exhibit improved thermostability, high glass transition temperature, are solvent resistant and are void-free. In addition, these curable materials are easily processed due to the large melt-cure window, low viscosity of the melt, low melting points of the biscitraconimides and the fact that curing can often be accomplished without additional solvents.
    • 含有至少一种具有通式(I)的双柠檬酰亚胺的可固化双酰亚胺组合物,其中D是二价基团,R是CH 2 -R 1,R 1独立地选自氢和具有1-18个碳原子的烷基; 至少一种烯属不饱和物质,和基于式(I)的双柠康酰亚胺的0-15摩尔%的选自双马来酰亚胺,柠康马来酰亚胺和衣康酸马来酰亚胺的可共性材料,其中式(I)的双柠康酰亚胺的摩尔比 对于烯属不饱和物质,为0.12〜4.0; 被披露。 还公开了双柠檬酰亚胺和烯属不饱和材料的共聚组合物,制备这些共聚物的方法和体现这些共聚物的制品​​。 这些共聚物表现出改善的热稳定性,高玻璃化转变温度,耐溶剂且无空隙。 此外,这些可固化材料由于熔融固化窗口大,熔融粘度低,二柠康酰亚胺的低熔点以及固化常常可以在没有其他溶剂的情况下完成的事实而易于加工。
