The possibility of a number of halatopolymers forming complexes with pyridine and their ability to produce ketones by pyrolytic decarboxylation have been investigated. Of all the halatopolymer‐forming divalent metal (i.e., Mg 2+ , Ca 2+ , Ba 2+ , Zn 2+ , Cd 2+ , Mn 2+ , and Pb 2+ ) dicarboxylates (i.e., suberate, sebacate, dodecanedioate, and terephthalate) investigated only Cd 2+ yielded polyalkylene ketone on pyrolysis and formed complexes with pyridine. The polyalkylene ketones were infusible, and no solvents were found for them which suggests a cross‐linked molecular structure. Complexes formed by the cadmium aliphatic dicarboxylates were unstable but highly viscous in solution. Cadmium‐pyridine terephthalate complexes were on the contrary very stable.
