Polymers from a wide variety of Lewis bases and metal-containing Lewis acids were formed from reaction of the metal halides employing the interfacial polycondensation system and commercially available reactants. Here we describe the synthesis of organotin polyamine esters from reaction of various organotin dihalides with the salt of 4-aminobenzoic acid, PABA. Yield generally increases as the organotin alkyl group increases in size when the organic liquid is heptane but decreases when the organic phase is carbon tetrachloride. Infrared spectroscopy shows bands characteristic of SnO and SnN bond formation. Bands characteristic of formation of the Sn-O-(C=O) unit are consistent with the product being largely of the non-bridged form with a non-symmetrical repeat unit prevalent, R-(C=O)Sn-N-R.
