The synthesis of organotin polyamine ethers was accomplished employing the classical interfacial polycondensation reaction between various organotin dichlorides and thiamine.  The reaction general occurring for all of the attempted organotin halides.  Reaction is rapid occurring in 15 seconds in moderate yield and giving moderate sized polymers with chain lengths ranging from 90 to 860. Infrared spectral, MALDI MS, and proton NMR results are consistent with the formation of Sn-N and Sn-O- linkages.
