    • Blends comprising(A.) at least one poly(aryl) ether ketone), and(B.) at least one polyimide having repeating units of the formula ##STR1## wherein R.sup.1 is a substituted or unsubstituted tetravalent radical having benzenoid unsaturation, andR.sup.2 is a substituted or unsubstituted divalent group having aromatic unsaturation which is essentially free of (i) backbone ether oxygen bonded directly to the aromatic ring forming an imide linkage and (ii) amide linkages bonded through carboxyl groups bonded to the aromatic ring forming an imide linkage. The blends exhibit good melt processability and wear resistance greater than the individual blend components.
    • 包含(A)至少一种聚(芳基)醚酮)和(B)至少一种具有下式重复单元的聚酰亚胺(I)的共混物,其中R 1是具有苯不饱和键的取代或未取代的四价基团 ,并且R 2是具有芳族不饱和键的取代或未取代的二价基团,其基本上不含(i)直接键合到形成酰亚胺键的芳环上的主链醚氧,和(ii)通过键合到芳环上的羧基键合的酰胺键 一个酰亚胺连接。 共混物表现出比单独的共混组分更好的熔融加工性和耐磨性。
