摘要： A polyimide oligomer of the formula wherein G is a group having a valence of t, each R is independently a C1-30 divalent bridging group, a C1-20 alkylene-X, or a C6-30 arylene-X wherein —X is —O-M′, —C(O)O-M′, —OC(O)O-M′, —S-M′, —S(O)2-M′, —S(O)3-M′, —OS(O)3-M′, or —OP(O)3-M′ wherein each M′ is independently Li, Na, K, Cs, Mg, Ca, Sr, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, B, Al, Ga, In, Ge, Sn, Pb, As, or Sb, provided that at least one R is C1-20 alkylene-X or C6-30 arylene-X, q is 0 or 1, m is 0 or 1, d is 0 or 1, p is 1 or 2, t is 1 to 6, and each n is independently 1 to 1,000, the total of all values of n is greater than 4, the polyimide oligomer is thermoplastic, and Q, M, D, and V are as provided herein.
