    摘要: Polyimide oligomers include (1) linear, monofunctional crosslinking oligomers prepared by condensing a monoanhydride end cap with a diamine that includes alternating ether and "sulfone" (-SO 2 -, -S-, -CO-, -(CF 3 ) 2 C-, or -(CH 3 ) 2 C-) linkages connecting alternating aromatic radicals and with a dianhydride (or dianhydride mixture), particularly the unsaturated, aliphatic dianhydride commonly known as MCTC; (2) linear, mono- or difunctional crosslinking oligomers prepared by condensing an amine end cap with a diamine and a dianhydride; and (3) multidimensional, crosslinking oligomers having an aromatic hub and at least three radiating arms connected to the hub, each arm including a crosslinking end cap at its distal end and at least one imide linkage.
    Blends, prepregs, and composites can be prepared from the oligomers.
    Multidimensional oligomers can be prepared using etheranhydride intermediates or etheramine intermediates formed by reacting a suitable hub with nitrophthalic anhydride or aminophenol.
