α，α′-二氰基-α，α ′-双氨基腈阴离子的缩合反应（二甲基氨基）-间二甲苯（8）与双[对-（对氟苯甲酰基）苯基]醚（9）与2，6-二溴吡啶（12）反应，得到相应的新的聚（双氨基腈）s聚{氧-对苯撑羰基-对苯撑-[α，α′-二氰基-α，α′-双聚[α，α′-二氰基-α，α ′-双（二甲氨基）-间二甲苯基-2，6-吡啶二基]（13）。易溶的聚（双氨基腈）10和13的酸水解使羰基脱保护，并分别得到新的聚酮聚（氧-对亚苯基羰基-对亚苯基羰基-间亚苯基羰基-对亚苯基）（PEKKK，11）和聚（羰基-间亚苯基羰基-2，6-吡啶二基）（14）。PEKKKK 11不溶于有机溶剂，但聚酮吡啶14可溶于酸性水介质。
Condensation of the dianion of the bisaminonitrile α,α′-dicyano-α,α′-bis(dimethylamino)-m-xylene (8) with bis[p-(p-fluorobenzoyl)phenyl] ether (9) and 2,6-dibromopyridine (12) yielded the corresponding new poly(bisaminonitrile)s poly{oxy-p-phenylenecarbonyl-p-phenylene-[α,α′-dicyano-α,α′-bis(dimethylamino)-m-xylyl]-p-phenylenecarbonyl-p-phenylene} (10) and poly[α,α′-dicyano-α,α′-bis(dimethylamino)-m-xylyl-2,6-pyridinediyl] (13), respectively. Acidic hydrolysis of the readily soluble poly(bisaminonitrile)s 10 and 13 deprotected the carbonyl groups and afforded the new polyketones poly(oxy-p-phenylenecarbonyl-p-phenylenecarbonyl-m-phenylenecarbonyl-p-phenylenecarbonyl-p-phenylene) (PEKKKK, 11) and poly(carbonyl-m-phenylenecarbonyl-2,6-pyridinediyl) (14), respectively. PEKKKK 11 is insoluble in organic solvents, but polyketopyridine 14 is soluble in acidic aqueous media.
